DatabaseMigrationService

Client

class DatabaseMigrationService.Client

A low-level client representing AWS Database Migration Service

Database Migration Service (DMS) can migrate your data to and from the most widely used commercial and open-source databases such as Oracle, PostgreSQL, Microsoft SQL Server, Amazon Redshift, MariaDB, Amazon Aurora, MySQL, and SAP Adaptive Server Enterprise (ASE). The service supports homogeneous migrations such as Oracle to Oracle, as well as heterogeneous migrations between different database platforms, such as Oracle to MySQL or SQL Server to PostgreSQL.

For more information about DMS, see What Is Database Migration Service? in the Database Migration Service User Guide.

import boto3

client = boto3.client('dms')

These are the available methods:

add_tags_to_resource(**kwargs)

Adds metadata tags to an DMS resource, including replication instance, endpoint, security group, and migration task. These tags can also be used with cost allocation reporting to track cost associated with DMS resources, or used in a Condition statement in an IAM policy for DMS. For more information, see ` Tag https://docs.aws.amazon.com/dms/latest/APIReference/API_Tag.html`__ data type description.

Request Syntax

response = client.add_tags_to_resource(
    ResourceArn='string',
    Tags=[
        {
            'Key': 'string',
            'Value': 'string',
            'ResourceArn': 'string'
        },
    ]
)
Parameters
  • ResourceArn (string) --

    [REQUIRED]

    Identifies the DMS resource to which tags should be added. The value for this parameter is an Amazon Resource Name (ARN).

    For DMS, you can tag a replication instance, an endpoint, or a replication task.

  • Tags (list) --

    [REQUIRED]

    One or more tags to be assigned to the resource.

    • (dict) --

      A user-defined key-value pair that describes metadata added to an DMS resource and that is used by operations such as the following:

      • AddTagsToResource
      • ListTagsForResource
      • RemoveTagsFromResource
      • Key (string) --

        A key is the required name of the tag. The string value can be 1-128 Unicode characters in length and can't be prefixed with "aws:" or "dms:". The string can only contain only the set of Unicode letters, digits, white-space, '_', '.', '/', '=', '+', '-' (Java regular expressions: "^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$").

      • Value (string) --

        A value is the optional value of the tag. The string value can be 1-256 Unicode characters in length and can't be prefixed with "aws:" or "dms:". The string can only contain only the set of Unicode letters, digits, white-space, '_', '.', '/', '=', '+', '-' (Java regular expressions: "^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$").

      • ResourceArn (string) --

        The Amazon Resource Name (ARN) string that uniquely identifies the resource for which the tag is created.

create_endpoint(**kwargs)

Creates an endpoint using the provided settings.

Note

For a MySQL source or target endpoint, don't explicitly specify the database using the DatabaseName request parameter on the CreateEndpoint API call. Specifying DatabaseName when you create a MySQL endpoint replicates all the task tables to this single database. For MySQL endpoints, you specify the database only when you specify the schema in the table-mapping rules of the DMS task.

      • Key (string) --

        A key is the required name of the tag. The string value can be 1-128 Unicode characters in length and can't be prefixed with "aws:" or "dms:". The string can only contain only the set of Unicode letters, digits, white-space, '_', '.', '/', '=', '+', '-' (Java regular expressions: "^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$").

      • Value (string) --

        A value is the optional value of the tag. The string value can be 1-256 Unicode characters in length and can't be prefixed with "aws:" or "dms:". The string can only contain only the set of Unicode letters, digits, white-space, '_', '.', '/', '=', '+', '-' (Java regular expressions: "^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$").

      • ResourceArn (string) --

        The Amazon Resource Name (ARN) string that uniquely identifies the resource for which the tag is created.

  • CertificateArn (string) -- The Amazon Resource Name (ARN) for the certificate.
  • SslMode (string) -- The Secure Sockets Layer (SSL) mode to use for the SSL connection. The default is none
  • ServiceAccessRoleArn (string) -- The Amazon Resource Name (ARN) for the service access role that you want to use to create the endpoint. The role must allow the iam:PassRole action.
  • ExternalTableDefinition (string) -- The external table definition.
  • DynamoDbSettings (dict) --

    Settings in JSON format for the target Amazon DynamoDB endpoint. For information about other available settings, see Using Object Mapping to Migrate Data to DynamoDB in the Database Migration Service User Guide.

      The Amazon Resource Name (ARN) used by the service to access the IAM role. The role must allow the iam:PassRole action.

  • S3Settings (dict) --

    Settings in JSON format for the target Amazon S3 endpoint. For more information about the available settings, see Extra Connection Attributes When Using Amazon S3 as a Target for DMS in the Database Migration Service User Guide.

    • ServiceAccessRoleArn (string) --

      The Amazon Resource Name (ARN) used by the service to access the IAM role. The role must allow the iam:PassRole action. It is a required parameter that enables DMS to write and read objects from an S3 bucket.

    • ExternalTableDefinition (string) --

      Specifies how tables are defined in the S3 source files only.

    • CsvRowDelimiter (string) --

      The delimiter used to separate rows in the .csv file for both source and target. The default is a carriage return (\n ).

    • CsvDelimiter (string) --

      The delimiter used to separate columns in the .csv file for both source and target. The default is a comma.

    • BucketFolder (string) --

      An optional parameter to set a folder name in the S3 bucket. If provided, tables are created in the path `` bucketFolder /schema_name /table_name /`` . If this parameter isn't specified, then the path used is `` schema_name /table_name /`` .

    • BucketName (string) --

      The name of the S3 bucket.

    • CompressionType (string) --

      An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Either set this parameter to NONE (the default) or don't use it to leave the files uncompressed. This parameter applies to both .csv and .parquet file formats.

    • EncryptionMode (string) --

      The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS .

      Note

      For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3 . But you can’t change the existing value from SSE_S3 to SSE_KMS .

      To use SSE_S3 , you need an Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:

      • s3:CreateBucket
      • s3:ListBucket
      • s3:DeleteBucket
      • s3:GetBucketLocation
      • s3:GetObject
      • s3:PutObject
      • s3:DeleteObject
      • s3:GetObjectVersion
      • s3:GetBucketPolicy
      • s3:PutBucketPolicy
      • s3:DeleteBucketPolicy
    • ServerSideEncryptionKmsKeyId (string) --

      If you are using SSE_KMS for the EncryptionMode , provide the KMS key ID. The key that you use needs an attached policy that enables Identity and Access Management (IAM) user permissions and allows use of the key.

      Here is a CLI example: ``aws dms create-endpoint --endpoint-identifier value --endpoint-type target --engine-name s3 --s3-settings ServiceAccessRoleArn=*value* ,BucketFolder=*value* ,BucketName=*value* ,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=*value* ``

    • DataFormat (string) --

      The format of the data that you want to use for output. You can choose one of the following:

      • csv : This is a row-based file format with comma-separated values (.csv).
      • parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.
    • EncodingType (string) --

      The type of encoding you are using:

      • RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
      • PLAIN doesn't use encoding at all. Values are stored as they are.
      • PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.
    • DictPageSizeLimit (integer) --

      The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN . This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.

    • RowGroupLength (integer) --

      The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.

      If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).

    • DataPageSize (integer) --

      The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.

    • ParquetVersion (string) --

      The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0 .

    • EnableStatistics (boolean) --

      A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL , DISTINCT , MAX , and MIN values. This parameter defaults to true . This value is used for .parquet file format only.

    • IncludeOpForFullLoad (boolean) --

      A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.

      Note

      DMS supports the IncludeOpForFullLoad parameter in versions 3.1.4 and later.

      For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y , the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.

      Note

      This setting works together with the CdcInsertsOnly and the CdcInsertsAndUpdates parameters for output to .csv files only. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide. .

    • CdcInsertsOnly (boolean) --

      A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.

      If CdcInsertsOnly is set to true or y , only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad . If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false , every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide. .

      Note

      DMS supports the interaction described preceding between the CdcInsertsOnly and IncludeOpForFullLoad parameters in versions 3.1.4 and later.

      CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.
    • TimestampColumnName (string) --

      A value that when nonblank causes DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.

      Note

      DMS supports the TimestampColumnName parameter in versions 3.1.4 and later.

      DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.

      For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.

      For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.

      The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS . By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.

      When the AddColumnName parameter is set to true , DMS also includes a name for the timestamp column that you set with TimestampColumnName .

    • ParquetTimestampInMillisecond (boolean) --

      A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.

      Note

      DMS supports the ParquetTimestampInMillisecond parameter in versions 3.1.4 and later.

      When ParquetTimestampInMillisecond is set to true or y , DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.

      Currently, Amazon Athena and Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or Glue.

      Note

      DMS writes any TIMESTAMP column values written to an S3 file in .csv format with microsecond precision.

      Setting ParquetTimestampInMillisecond has no effect on the string format of the timestamp column value that is inserted by setting the TimestampColumnName parameter.

    • CdcInsertsAndUpdates (boolean) --

      A value that enables a change data capture (CDC) load to write INSERT and UPDATE operations to .csv or .parquet (columnar storage) output files. The default setting is false , but when CdcInsertsAndUpdates is set to true or y , only INSERTs and UPDATEs from the source database are migrated to the .csv or .parquet file.

      For .csv file format only, how these INSERTs and UPDATEs are recorded depends on the value of the IncludeOpForFullLoad parameter. If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to either I or U to indicate INSERT and UPDATE operations at the source. But if IncludeOpForFullLoad is set to false , CDC records are written without an indication of INSERT or UPDATE operations at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide. .

      Note

      DMS supports the use of the CdcInsertsAndUpdates parameter in versions 3.3.1 and later.

      CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.
    • DatePartitionEnabled (boolean) --

      When set to true , this parameter partitions S3 bucket folders based on transaction commit dates. The default value is false . For more information about date-based folder partitioning, see Using date-based folder partitioning .

    • DatePartitionSequence (string) --

      Identifies the sequence of the date format to use during folder partitioning. The default value is YYYYMMDD . Use this parameter when DatePartitionedEnabled is set to true .

    • DatePartitionDelimiter (string) --

      Specifies a date separating delimiter to use during folder partitioning. The default value is SLASH . Use this parameter when DatePartitionedEnabled is set to true .

    • UseCsvNoSupValue (boolean) --

      This setting applies if the S3 output files during a change data capture (CDC) load are written in .csv format. If set to true for columns not included in the supplemental log, DMS uses the value specified by ` CsvNoSupValue https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-CsvNoSupValue`__ . If not set or set to false , DMS uses the null value for these columns.

      Note

      This setting is supported in DMS versions 3.4.1 and later.

    • CsvNoSupValue (string) --

      This setting only applies if your Amazon S3 output files during a change data capture (CDC) load are written in .csv format. If ` UseCsvNoSupValue https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-UseCsvNoSupValue`__ is set to true, specify a string value that you want DMS to use for all columns not included in the supplemental log. If you do not specify a string value, DMS uses the null value for these columns regardless of the UseCsvNoSupValue setting.

      Note

      This setting is supported in DMS versions 3.4.1 and later.

    • PreserveTransactions (boolean) --

      If set to true , DMS saves the transaction order for a change data capture (CDC) load on the Amazon S3 target specified by ` CdcPath https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-CdcPath`__ . For more information, see Capturing data changes (CDC) including transaction order on the S3 target .

      Note

      This setting is supported in DMS versions 3.4.2 and later.

    • CdcPath (string) --

      Specifies the folder path of CDC files. For an S3 source, this setting is required if a task captures change data; otherwise, it's optional. If CdcPath is set, DMS reads CDC files from this path and replicates the data changes to the target endpoint. For an S3 target if you set ` PreserveTransactions https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-PreserveTransactions`__ to true , DMS verifies that you have set this parameter to a folder path on your S3 target where DMS can save the transaction order for the CDC load. DMS creates this CDC folder path in either your S3 target working directory or the S3 target location specified by ` BucketFolder https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-BucketFolder`__ and ` BucketName https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-BucketName`__ .

      For example, if you specify CdcPath as MyChangedData , and you specify BucketName as MyTargetBucket but do not specify BucketFolder , DMS creates the CDC folder path following: MyTargetBucket/MyChangedData .

      If you specify the same CdcPath , and you specify BucketName as MyTargetBucket and BucketFolder as MyTargetData , DMS creates the CDC folder path following: MyTargetBucket/MyTargetData/MyChangedData .

      For more information on CDC including transaction order on an S3 target, see Capturing data changes (CDC) including transaction order on the S3 target .

      Note

      This setting is supported in DMS versions 3.4.2 and later.

    • CannedAclForObjects (string) --

      A value that enables DMS to specify a predefined (canned) access control list for objects created in an Amazon S3 bucket as .csv or .parquet files. For more information about Amazon S3 canned ACLs, see Canned ACL in the Amazon S3 Developer Guide.

      The default value is NONE. Valid values include NONE, PRIVATE, PUBLIC_READ, PUBLIC_READ_WRITE, AUTHENTICATED_READ, AWS_EXEC_READ, BUCKET_OWNER_READ, and BUCKET_OWNER_FULL_CONTROL.

    • AddColumnName (boolean) --

      An optional parameter that, when set to true or y , you can use to add column name information to the .csv output file.

      The default value is false . Valid values are true , false , y , and n .

    • CdcMaxBatchInterval (integer) --

      Maximum length of the interval, defined in seconds, after which to output a file to Amazon S3.

      When CdcMaxBatchInterval and CdcMinFileSize are both specified, the file write is triggered by whichever parameter condition is met first within an DMS CloudFormation template.

      The default value is 60 seconds.

    • CdcMinFileSize (integer) --

      Minimum file size, defined in megabytes, to reach for a file output to Amazon S3.

      When CdcMinFileSize and CdcMaxBatchInterval are both specified, the file write is triggered by whichever parameter condition is met first within an DMS CloudFormation template.

      The default value is 32 MB.

    • CsvNullValue (string) --

      An optional parameter that specifies how DMS treats null values. While handling the null value, you can use this parameter to pass a user-defined string as null when writing to the target. For example, when target columns are not nullable, you can use this option to differentiate between the empty string value and the null value. So, if you set this parameter value to the empty string ("" or ''), DMS treats the empty string as the null value instead of NULL .

      The default value is NULL . Valid values include any valid string.

    • IgnoreHeaderRows (integer) --

      When this value is set to 1, DMS ignores the first row header in a .csv file. A value of 1 turns on the feature; a value of 0 turns off the feature.

      The default is 0.

    • MaxFileSize (integer) --

      A value that specifies the maximum size (in KB) of any .csv file to be created while migrating to an S3 target during full load.

      The default value is 1,048,576 KB (1 GB). Valid values include 1 to 1,048,576.

    • Rfc4180 (boolean) --

      For an S3 source, when this value is set to true or y , each leading double quotation mark has to be followed by an ending double quotation mark. This formatting complies with RFC 4180. When this value is set to false or n , string literals are copied to the target as is. In this case, a delimiter (row or column) signals the end of the field. Thus, you can't use a delimiter as part of the string, because it signals the end of the value.

      For an S3 target, an optional parameter used to set behavior to comply with RFC 4180 for data migrated to Amazon S3 using .csv file format only. When this value is set to true or y using Amazon S3 as a target, if the data has quotation marks or newline characters in it, DMS encloses the entire column with an additional pair of double quotation marks ("). Every quotation mark within the data is repeated twice.

      The default value is true . Valid values include true , false , y , and n .

  • DmsTransferSettings (dict) --

    The settings in JSON format for the DMS transfer type of source endpoint.

    Possible settings include the following:

    • ServiceAccessRoleArn - The Amazon Resource Name (ARN) used by the service access IAM role. The role must allow the iam:PassRole action.
    • BucketName - The name of the S3 bucket to use.

    Shorthand syntax for these settings is as follows: ServiceAccessRoleArn=string,BucketName=string

    JSON syntax for these settings is as follows: { "ServiceAccessRoleArn": "string", "BucketName": "string", }

    • AuthMechanism (string) --

      The authentication mechanism you use to access the MongoDB source endpoint.

      For the default value, in MongoDB version 2.x, "default" is "mongodb_cr" . For MongoDB version 3.x or later, "default" is "scram_sha_1" . This setting isn't used when AuthType is set to "no" .

    • NestingLevel (string) --

      Specifies either document or table mode.

      Default value is "none" . Specify "none" to use document mode. Specify "one" to use table mode.

      When set to true , this value causes a task to fail if the actual size of a LOB column is greater than the specified LobMaxSize .

      If task is set to Limited LOB mode and this option is set to true, the task fails instead of truncating the LOB data.

    • HeartbeatEnable (boolean) --

      The write-ahead log (WAL) heartbeat feature mimics a dummy transaction. By doing this, it prevents idle logical replication slots from holding onto old WAL logs, which can result in storage full situations on the source. This heartbeat keeps restart_lsn moving and prevents storage full scenarios.

    • HeartbeatSchema (string) --

      Sets the schema in which the heartbeat artifacts are created.

    • HeartbeatFrequency (integer) --

      Sets the WAL heartbeat frequency (in minutes).

    • CleanSourceMetadataOnMismatch (boolean) --

      Adjusts the behavior of DMS when migrating from an SQL Server source database that is hosted as part of an Always On availability group cluster. If you need DMS to poll all the nodes in the Always On cluster for transaction backups, set this attribute to false .

    • DatabaseName (string) --

      Database name for the endpoint. For a MySQL source or target endpoint, don't explicitly specify the database using the DatabaseName request parameter on either the CreateEndpoint or ModifyEndpoint API call. Specifying DatabaseName when you create or modify a MySQL endpoint replicates all the task tables to this single database. For MySQL endpoints, you specify the database only when you specify the schema in the table-mapping rules of the DMS task.

    • EventsPollInterval (integer) --

      Specifies how often to check the binary log for new changes/events when the database is idle.

    • Password (string) --

      Endpoint connection password.

    • Port (integer) --

      Endpoint TCP port.

    • ServerName (string) --

      Fully qualified domain name of the endpoint.

    • AddSupplementalLogging (boolean) --

      Set this attribute to set up table-level supplemental logging for the Oracle database. This attribute enables PRIMARY KEY supplemental logging on all tables selected for a migration task.

      If you use this option, you still need to enable database-level supplemental logging.

    • ArchivedLogDestId (integer) --

      Specifies the ID of the destination for the archived redo logs. This value should be the same as a number in the dest_id column of the v$archived_log view. If you work with an additional redo log destination, use the AdditionalArchivedLogDestId option to specify the additional destination ID. Doing this improves performance by ensuring that the correct logs are accessed from the outset.

    • AdditionalArchivedLogDestId (integer) --

      Set this attribute with ArchivedLogDestId in a primary/ standby setup. This attribute is useful in the case of a switchover. In this case, DMS needs to know which destination to get archive redo logs from to read changes. This need arises because the previous primary instance is now a standby instance after switchover.

      Although DMS supports the use of the Oracle RESETLOGS option to open the database, never use RESETLOGS unless necessary. For additional information about RESETLOGS , see RMAN Data Repair Concepts in the Oracle Database Backup and Recovery User's Guide .

    • ExtraArchivedLogDestIds (list) --

      Specifies the IDs of one more destinations for one or more archived redo logs. These IDs are the values of the dest_id column in the v$archived_log view. Use this setting with the archivedLogDestId extra connection attribute in a primary-to-single setup or a primary-to-multiple-standby setup.

      This setting is useful in a switchover when you use an Oracle Data Guard database as a source. In this case, DMS needs information about what destination to get archive redo logs from to read changes. DMS needs this because after the switchover the previous primary is a standby instance. For example, in a primary-to-single standby setup you might apply the following settings.

      archivedLogDestId=1; ExtraArchivedLogDestIds=[2]

      In a primary-to-multiple-standby setup, you might apply the following settings.

      archivedLogDestId=1; ExtraArchivedLogDestIds=[2,3,4]

      Although DMS supports the use of the Oracle RESETLOGS option to open the database, never use RESETLOGS unless it's necessary. For more information about RESETLOGS , see RMAN Data Repair Concepts in the Oracle Database Backup and Recovery User's Guide .

    • ReadBackupOnly (boolean) --

      When this attribute is set to Y , DMS only reads changes from transaction log backups and doesn't read from the active transaction log file during ongoing replication. Setting this parameter to Y enables you to control active transaction log file growth during full load and ongoing replication tasks. However, it can add some source latency to ongoing replication.

    • SafeguardPolicy (string) --

      Use this attribute to minimize the need to access the backup log and enable DMS to prevent truncation using one of the following two methods.

      Start transactions in the database: This is the default method. When this method is used, DMS prevents TLOG truncation by mimicking a transaction in the database. As long as such a transaction is open, changes that appear after the transaction started aren't truncated. If you need Microsoft Replication to be enabled in your database, then you must choose this method.

      Exclusively use sp_repldone within a single task : When this method is used, DMS reads the changes and then uses sp_repldone to mark the TLOG transactions as ready for truncation. Although this method doesn't involve any transactional activities, it can only be used when Microsoft Replication isn't running. Also, when using this method, only one DMS task can access the database at any given time. Therefore, if you need to run parallel DMS tasks against the same database, use the default method.

        The external table definition.

      • ExternalId (string) --

        Value returned by a call to CreateEndpoint that can be used for cross-account validation. Use it on a subsequent call to CreateEndpoint to create the endpoint with a cross-account.

      • DynamoDbSettings (dict) --

        The settings for the DynamoDB target endpoint. For more information, see the DynamoDBSettings structure.

        • ServiceAccessRoleArn (string) --

          The Amazon Resource Name (ARN) used by the service to access the IAM role. The role must allow the iam:PassRole action.

      • S3Settings (dict) --

        The settings for the S3 target endpoint. For more information, see the S3Settings structure.

        • ServiceAccessRoleArn (string) --

          The Amazon Resource Name (ARN) used by the service to access the IAM role. The role must allow the iam:PassRole action. It is a required parameter that enables DMS to write and read objects from an S3 bucket.

        • ExternalTableDefinition (string) --

          Specifies how tables are defined in the S3 source files only.

        • CsvRowDelimiter (string) --

          The delimiter used to separate rows in the .csv file for both source and target. The default is a carriage return (\n ).

        • CsvDelimiter (string) --

          The delimiter used to separate columns in the .csv file for both source and target. The default is a comma.

        • BucketFolder (string) --

          An optional parameter to set a folder name in the S3 bucket. If provided, tables are created in the path `` bucketFolder /schema_name /table_name /`` . If this parameter isn't specified, then the path used is `` schema_name /table_name /`` .

        • BucketName (string) --

          The name of the S3 bucket.

        • CompressionType (string) --

          An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Either set this parameter to NONE (the default) or don't use it to leave the files uncompressed. This parameter applies to both .csv and .parquet file formats.

        • EncryptionMode (string) --

          The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS .

          Note

          For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3 . But you can’t change the existing value from SSE_S3 to SSE_KMS .

          To use SSE_S3 , you need an Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:

          • s3:CreateBucket
          • s3:ListBucket
          • s3:DeleteBucket
          • s3:GetBucketLocation
          • s3:GetObject
          • s3:PutObject
          • s3:DeleteObject
          • s3:GetObjectVersion
          • s3:GetBucketPolicy
          • s3:PutBucketPolicy
          • s3:DeleteBucketPolicy
        • ServerSideEncryptionKmsKeyId (string) --

          If you are using SSE_KMS for the EncryptionMode , provide the KMS key ID. The key that you use needs an attached policy that enables Identity and Access Management (IAM) user permissions and allows use of the key.

          Here is a CLI example: ``aws dms create-endpoint --endpoint-identifier value --endpoint-type target --engine-name s3 --s3-settings ServiceAccessRoleArn=*value* ,BucketFolder=*value* ,BucketName=*value* ,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=*value* ``

        • DataFormat (string) --

          The format of the data that you want to use for output. You can choose one of the following:

          • csv : This is a row-based file format with comma-separated values (.csv).
          • parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.
        • EncodingType (string) --

          The type of encoding you are using:

          • RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
          • PLAIN doesn't use encoding at all. Values are stored as they are.
          • PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.
        • DictPageSizeLimit (integer) --

          The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN . This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.

        • RowGroupLength (integer) --

          The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.

          If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).

        • DataPageSize (integer) --

          The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.

        • ParquetVersion (string) --

          The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0 .

        • EnableStatistics (boolean) --

          A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL , DISTINCT , MAX , and MIN values. This parameter defaults to true . This value is used for .parquet file format only.

        • IncludeOpForFullLoad (boolean) --

          A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.

          Note

          DMS supports the IncludeOpForFullLoad parameter in versions 3.1.4 and later.

          For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y , the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.

          Note

          This setting works together with the CdcInsertsOnly and the CdcInsertsAndUpdates parameters for output to .csv files only. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide. .

        • CdcInsertsOnly (boolean) --

          A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.

          If CdcInsertsOnly is set to true or y , only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad . If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false , every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide. .

          Note

          DMS supports the interaction described preceding between the CdcInsertsOnly and IncludeOpForFullLoad parameters in versions 3.1.4 and later.

          CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.

        • TimestampColumnName (string) --

          A value that when nonblank causes DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.

          Note

          DMS supports the TimestampColumnName parameter in versions 3.1.4 and later.

          DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.

          For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.

          For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.

          The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS . By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.

          When the AddColumnName parameter is set to true , DMS also includes a name for the timestamp column that you set with TimestampColumnName .

        • ParquetTimestampInMillisecond (boolean) --

          A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.

          Note

          DMS supports the ParquetTimestampInMillisecond parameter in versions 3.1.4 and later.

          When ParquetTimestampInMillisecond is set to true or y , DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.

          Currently, Amazon Athena and Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or Glue.

          Note

          DMS writes any TIMESTAMP column values written to an S3 file in .csv format with microsecond precision.

          Setting ParquetTimestampInMillisecond has no effect on the string format of the timestamp column value that is inserted by setting the TimestampColumnName parameter.

        • CdcInsertsAndUpdates (boolean) --

          A value that enables a change data capture (CDC) load to write INSERT and UPDATE operations to .csv or .parquet (columnar storage) output files. The default setting is false , but when CdcInsertsAndUpdates is set to true or y , only INSERTs and UPDATEs from the source database are migrated to the .csv or .parquet file.

          For .csv file format only, how these INSERTs and UPDATEs are recorded depends on the value of the IncludeOpForFullLoad parameter. If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to either I or U to indicate INSERT and UPDATE operations at the source. But if IncludeOpForFullLoad is set to false , CDC records are written without an indication of INSERT or UPDATE operations at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide. .

          Note

          DMS supports the use of the CdcInsertsAndUpdates parameter in versions 3.3.1 and later.

          CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.

        • DatePartitionEnabled (boolean) --

          When set to true , this parameter partitions S3 bucket folders based on transaction commit dates. The default value is false . For more information about date-based folder partitioning, see Using date-based folder partitioning .

        • DatePartitionSequence (string) --

          Identifies the sequence of the date format to use during folder partitioning. The default value is YYYYMMDD . Use this parameter when DatePartitionedEnabled is set to true .

        • DatePartitionDelimiter (string) --

          Specifies a date separating delimiter to use during folder partitioning. The default value is SLASH . Use this parameter when DatePartitionedEnabled is set to true .

        • UseCsvNoSupValue (boolean) --

          This setting applies if the S3 output files during a change data capture (CDC) load are written in .csv format. If set to true for columns not included in the supplemental log, DMS uses the value specified by ` CsvNoSupValue https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-CsvNoSupValue`__ . If not set or set to false , DMS uses the null value for these columns.

          Note

          This setting is supported in DMS versions 3.4.1 and later.

        • CsvNoSupValue (string) --

          This setting only applies if your Amazon S3 output files during a change data capture (CDC) load are written in .csv format. If ` UseCsvNoSupValue https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-UseCsvNoSupValue`__ is set to true, specify a string value that you want DMS to use for all columns not included in the supplemental log. If you do not specify a string value, DMS uses the null value for these columns regardless of the UseCsvNoSupValue setting.

          Note

          This setting is supported in DMS versions 3.4.1 and later.

        • PreserveTransactions (boolean) --

          If set to true , DMS saves the transaction order for a change data capture (CDC) load on the Amazon S3 target specified by ` CdcPath https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-CdcPath`__ . For more information, see Capturing data changes (CDC) including transaction order on the S3 target .

          Note

          This setting is supported in DMS versions 3.4.2 and later.

        • CdcPath (string) --

          Specifies the folder path of CDC files. For an S3 source, this setting is required if a task captures change data; otherwise, it's optional. If CdcPath is set, DMS reads CDC files from this path and replicates the data changes to the target endpoint. For an S3 target if you set ` PreserveTransactions https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-PreserveTransactions`__ to true , DMS verifies that you have set this parameter to a folder path on your S3 target where DMS can save the transaction order for the CDC load. DMS creates this CDC folder path in either your S3 target working directory or the S3 target location specified by ` BucketFolder https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-BucketFolder`__ and ` BucketName https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-BucketName`__ .

          For example, if you specify CdcPath as MyChangedData , and you specify BucketName as MyTargetBucket but do not specify BucketFolder , DMS creates the CDC folder path following: MyTargetBucket/MyChangedData .

          If you specify the same CdcPath , and you specify BucketName as MyTargetBucket and BucketFolder as MyTargetData , DMS creates the CDC folder path following: MyTargetBucket/MyTargetData/MyChangedData .

          For more information on CDC including transaction order on an S3 target, see Capturing data changes (CDC) including transaction order on the S3 target .

          Note

          This setting is supported in DMS versions 3.4.2 and later.

        • CannedAclForObjects (string) --

          A value that enables DMS to specify a predefined (canned) access control list for objects created in an Amazon S3 bucket as .csv or .parquet files. For more information about Amazon S3 canned ACLs, see Canned ACL in the Amazon S3 Developer Guide.

          The default value is NONE. Valid values include NONE, PRIVATE, PUBLIC_READ, PUBLIC_READ_WRITE, AUTHENTICATED_READ, AWS_EXEC_READ, BUCKET_OWNER_READ, and BUCKET_OWNER_FULL_CONTROL.

        • AddColumnName (boolean) --

          An optional parameter that, when set to true or y , you can use to add column name information to the .csv output file.

          The default value is false . Valid values are true , false , y , and n .

        • CdcMaxBatchInterval (integer) --

          Maximum length of the interval, defined in seconds, after which to output a file to Amazon S3.

          When CdcMaxBatchInterval and CdcMinFileSize are both specified, the file write is triggered by whichever parameter condition is met first within an DMS CloudFormation template.

          The default value is 60 seconds.

        • CdcMinFileSize (integer) --

          Minimum file size, defined in megabytes, to reach for a file output to Amazon S3.

          When CdcMinFileSize and CdcMaxBatchInterval are both specified, the file write is triggered by whichever parameter condition is met first within an DMS CloudFormation template.

          The default value is 32 MB.

        • CsvNullValue (string) --

          An optional parameter that specifies how DMS treats null values. While handling the null value, you can use this parameter to pass a user-defined string as null when writing to the target. For example, when target columns are not nullable, you can use this option to differentiate between the empty string value and the null value. So, if you set this parameter value to the empty string ("" or ''), DMS treats the empty string as the null value instead of NULL .

          The default value is NULL . Valid values include any valid string.

        • IgnoreHeaderRows (integer) --

          When this value is set to 1, DMS ignores the first row header in a .csv file. A value of 1 turns on the feature; a value of 0 turns off the feature.

          The default is 0.

        • MaxFileSize (integer) --

          A value that specifies the maximum size (in KB) of any .csv file to be created while migrating to an S3 target during full load.

          The default value is 1,048,576 KB (1 GB). Valid values include 1 to 1,048,576.

        • Rfc4180 (boolean) --

          For an S3 source, when this value is set to true or y , each leading double quotation mark has to be followed by an ending double quotation mark. This formatting complies with RFC 4180. When this value is set to false or n , string literals are copied to the target as is. In this case, a delimiter (row or column) signals the end of the field. Thus, you can't use a delimiter as part of the string, because it signals the end of the value.

          For an S3 target, an optional parameter used to set behavior to comply with RFC 4180 for data migrated to Amazon S3 using .csv file format only. When this value is set to true or y using Amazon S3 as a target, if the data has quotation marks or newline characters in it, DMS encloses the entire column with an additional pair of double quotation marks ("). Every quotation mark within the data is repeated twice.

          The default value is true . Valid values include true , false , y , and n .

        • PartitionIncludeSchemaTable (boolean) --

          Prefixes schema and table names to partition values, when the partition type is primary-key-type . Doing this increases data distribution among Kafka partitions. For example, suppose that a SysBench schema has thousands of tables and each table has only limited range for a primary key. In this case, the same primary key is sent from thousands of tables to the same partition, which causes throttling. The default is false .

        • IncludeTableAlterOperations (boolean) --

          Includes any data definition language (DDL) operations that change the table in the control data, such as rename-table , drop-table , add-column , drop-column , and rename-column . The default is false .

          The maximum percentage of records that can fail to be written before a full load operation stops.

          To avoid early failure, this counter is only effective after 1000 records are transferred. Elasticsearch also has the concept of error monitoring during the last 10 minutes of an Observation Window. If transfer of all records fail in the last 10 minutes, the full load operation stops.

        • ErrorRetryDuration (integer) --

          The maximum number of seconds for which DMS retries failed API requests to the Elasticsearch cluster.

      • NeptuneSettings (dict) --

        • MaxRetryCount (integer) --

          The number of times for DMS to retry a bulk load of migrated graph data to the Neptune target database before raising an error. The default is 5.

        • IamAuthEnabled (boolean) --

          If you want Identity and Access Management (IAM) authorization enabled for this endpoint, set this parameter to true . Then attach the appropriate IAM policy document to your service role specified by ServiceAccessRoleArn . The default is false .

          This parameter applies only to TIMESTAMP and DATE columns. Always use ACCEPTANYDATE with the DATEFORMAT parameter. If the date format for the data doesn't match the DATEFORMAT specification, Amazon Redshift inserts a NULL value into that field.

        • AfterConnectScript (string) --

          Code to run after connecting. This parameter should contain the code itself, not the name of a file containing the code.

        • BucketFolder (string) --

          An S3 folder where the comma-separated-value (.csv) files are stored before being uploaded to the target Redshift cluster.

          For full load mode, DMS converts source records into .csv files and loads them to the BucketFolder/TableID path. DMS uses the Redshift COPY command to upload the .csv files to the target table. The files are deleted once the COPY operation has finished. For more information, see COPY in the Amazon Redshift Database Developer Guide .

          For change-data-capture (CDC) mode, DMS creates a NetChanges table, and loads the .csv files to this BucketFolder/NetChangesTableID path.

        • BucketName (string) --

          The name of the intermediate S3 bucket used to store .csv files before uploading data to Redshift.

        • CompUpdate (boolean) --

          If you set CompUpdate to true Amazon Redshift applies automatic compression if the table is empty. This applies even if the table columns already have encodings other than RAW . If you set CompUpdate to false , automatic compression is disabled and existing column encodings aren't changed. The default is true .

        • ConnectionTimeout (integer) --

          A value that sets the amount of time to wait (in milliseconds) before timing out, beginning from when you initially establish a connection.

        • DatabaseName (string) --

          The name of the Amazon Redshift data warehouse (service) that you are working with.

        • DateFormat (string) --

          The date format that you are using. Valid values are auto (case-sensitive), your date format string enclosed in quotes, or NULL. If this parameter is left unset (NULL), it defaults to a format of 'YYYY-MM-DD'. Using auto recognizes most strings, even some that aren't supported when you use a date format string.

          If your date and time values use formats different from each other, set this to auto .

        • EmptyAsNull (boolean) --

          A value that specifies whether DMS should migrate empty CHAR and VARCHAR fields as NULL. A value of true sets empty CHAR and VARCHAR fields to null. The default is false .

        • EncryptionMode (string) --

          The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS .

          Note

          For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3 . But you can’t change the existing value from SSE_S3 to SSE_KMS .

          When set to true , this value causes a task to fail if the actual size of a LOB column is greater than the specified LobMaxSize .

          If task is set to Limited LOB mode and this option is set to true, the task fails instead of truncating the LOB data.

        • HeartbeatEnable (boolean) --

          The write-ahead log (WAL) heartbeat feature mimics a dummy transaction. By doing this, it prevents idle logical replication slots from holding onto old WAL logs, which can result in storage full situations on the source. This heartbeat keeps restart_lsn moving and prevents storage full scenarios.

        • HeartbeatSchema (string) --

          Sets the schema in which the heartbeat artifacts are created.

        • HeartbeatFrequency (integer) --

          Sets the WAL heartbeat frequency (in minutes).

        • CleanSourceMetadataOnMismatch (boolean) --

          Adjusts the behavior of DMS when migrating from an SQL Server source database that is hosted as part of an Always On availability group cluster. If you need DMS to poll all the nodes in the Always On cluster for transaction backups, set this attribute to false .

        • DatabaseName (string) --

          Database name for the endpoint. For a MySQL source or target endpoint, don't explicitly specify the database using the DatabaseName request parameter on either the CreateEndpoint or ModifyEndpoint API call.

          Endpoint connection user name.

        • SecretsManagerAccessRoleArn (string) --

          The full Amazon Resource Name (ARN) of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret . The role must allow the iam:PassRole action. SecretsManagerSecret has the value of the Amazon Web Services Secrets Manager secret that allows access to the MySQL endpoint.

          Note

          You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerSecretId . Or you can specify clear-text values for UserName , Password , ServerName , and Port . You can't specify both. For more information on creating this SecretsManagerSecret and the SecretsManagerAccessRoleArn and SecretsManagerSecretId required to access it, see Using secrets to access Database Migration Service resources in the Database Migration Service User Guide .

        The settings for the Oracle source and target endpoint. For more information, see the OracleSettings structure.

        • AddSupplementalLogging (boolean) --

          Set this attribute to set up table-level supplemental logging for the Oracle database. This attribute enables PRIMARY KEY supplemental logging on all tables selected for a migration task.

          If you use this option, you still need to enable database-level supplemental logging.

        • ArchivedLogDestId (integer) --

          Specifies the ID of the destination for the archived redo logs. This value should be the same as a number in the dest_id column of the v$archived_log view. If you work with an additional redo log destination, use the AdditionalArchivedLogDestId option to specify the additional destination ID. Doing this improves performance by ensuring that the correct logs are accessed from the outset.

        • AdditionalArchivedLogDestId (integer) --

          Set this attribute with ArchivedLogDestId in a primary/ standby setup. This attribute is useful in the case of a switchover. In this case, DMS needs to know which destination to get archive redo logs from to read changes. This need arises because the previous primary instance is now a standby instance after switchover.

          Although DMS supports the use of the Oracle RESETLOGS option to open the database, never use RESETLOGS unless necessary. For additional information about RESETLOGS , see RMAN Data Repair Concepts in the Oracle Database Backup and Recovery User's Guide .

        • ExtraArchivedLogDestIds (list) --

          Specifies the IDs of one more destinations for one or more archived redo logs. These IDs are the values of the dest_id column in the v$archived_log view. Use this setting with the archivedLogDestId extra connection attribute in a primary-to-single setup or a primary-to-multiple-standby setup.

          This setting is useful in a switchover when you use an Oracle Data Guard database as a source. In this case, DMS needs information about what destination to get archive redo logs from to read changes. DMS needs this because after the switchover the previous primary is a standby instance. For example, in a primary-to-single standby setup you might apply the following settings.

          archivedLogDestId=1; ExtraArchivedLogDestIds=[2]

          In a primary-to-multiple-standby setup, you might apply the following settings.

          archivedLogDestId=1; ExtraArchivedLogDestIds=[2,3,4]

          Although DMS supports the use of the Oracle RESETLOGS option to open the database, never use RESETLOGS unless it's necessary. For more information about RESETLOGS , see RMAN Data Repair Concepts in the Oracle Database Backup and Recovery User's Guide .

        • DatabaseName (string) --

          Database name for the endpoint.

        • ControlTablesFileGroup (string) --

          Specifies a file group for the DMS internal tables. When the replication task starts, all the internal DMS control tables (awsdms_ apply_exception, awsdms_apply, awsdms_changes) are created for the specified file group.

        • Password (string) --

          Endpoint connection password.

        • QuerySingleAlwaysOnNode (boolean) --

          Cleans and recreates table metadata information on the replication instance when a mismatch occurs. An example is a situation where running an alter DDL statement on a table might result in different information about the table cached in the replication instance.

        • ReadBackupOnly (boolean) --

          When this attribute is set to Y , DMS only reads changes from transaction log backups and doesn't read from the active transaction log file during ongoing replication. Setting this parameter to Y enables you to control active transaction log file growth during full load and ongoing replication tasks. However, it can add some source latency to ongoing replication.

        • SafeguardPolicy (string) --

          Use this attribute to minimize the need to access the backup log and enable DMS to prevent truncation using one of the following two methods.

          Start transactions in the database: This is the default method. When this method is used, DMS prevents TLOG truncation by mimicking a transaction in the database. As long as such a transaction is open, changes that appear after the transaction started aren't truncated. If you need Microsoft Replication to be enabled in your database, then you must choose this method.

          Exclusively use sp_repldone within a single task : When this method is used, DMS reads the changes and then uses sp_repldone to mark the TLOG transactions as ready for truncation. Although this method doesn't involve any transactional activities, it can only be used when Microsoft Replication isn't running. Also, when using this method, only one DMS task can access the database at any given time. Therefore, if you need to run parallel DMS tasks against the same database, use the default method.

        • ServerName (string) --

          Fully qualified domain name of the endpoint.

        • Username (string) --

          Endpoint connection user name.

        • UseBcpFullLoad (boolean) --

          Use this to attribute to transfer data for full-load operations using BCP. When the target table contains an identity column that does not exist in the source table, you must disable the use BCP for loading table option.

        • UseThirdPartyBackupDevice (boolean) --

          When this attribute is set to Y , DMS processes third-party transaction log backups if they are created in native format.

        • SecretsManagerAccessRoleArn (string) --

          The full Amazon Resource Name (ARN) of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret . The role must allow the iam:PassRole action. SecretsManagerSecret has the value of the Amazon Web Services Secrets Manager secret that allows access to the SQL Server endpoint.

          Note

  • ResourceIdentifier (string) -- A friendly name for the resource identifier at the end of the EndpointArn response parameter that is returned in the created Endpoint object. The value for this parameter can have up to 31 characters. It can contain only ASCII letters, digits, and hyphen ('-'). Also, it can't end with a hyphen or contain two consecutive hyphens, and can only begin with a letter, such as Example-App-ARN1 . For example, this value might result in the EndpointArn value arn:aws:dms:eu-west-1:012345678901:rep:Example-App-ARN1 . If you don't specify a ResourceIdentifier value, DMS generates a default identifier value for the end of EndpointArn .

        Note

        ` StartReplicationTaskAssessmentRun https://docs.aws.amazon.com/dms/latest/APIReference/API_StartReplicationTaskAssessmentRun.html`__ is an improved premigration task assessment operation. The ` StartReplicationTaskAssessment https://docs.aws.amazon.com/dms/latest/APIReference/API_StartReplicationTaskAssessment.html`__ operation assesses data type compatibility only between the source and target database of a given migration task. In contrast, ` StartReplicationTaskAssessmentRun https://docs.aws.amazon.com/dms/latest/APIReference/API_StartReplicationTaskAssessmentRun.html`__ enables you to specify a variety of premigration task assessments in addition to data type compatibility. These assessments include ones for the validity of primary key definitions and likely issues with database migration performance, among others.

      • LastFailureMessage (string) --

        The last error (failure) message generated for the replication task.

        • "STOP_REASON_CACHED_CHANGES_NOT_APPLIED" – In a full-load and CDC migration, the full load stopped as specified before starting the CDC migration.
        • "STOP_REASON_SERVER_TIME" – The migration stopped at the specified server time.
      • ReplicationTaskCreationDate (datetime) --

        The date the replication task was created.

      • ReplicationTaskStartDate (datetime) --

        The date the replication task is scheduled to start.

      • CdcStartPosition (string) --

        Indicates when you want a change data capture (CDC) operation to start. Use either CdcStartPosition or CdcStartTime to specify when you want the CDC operation to start. Specifying both values results in an error.

        The external table definition.

      • ExternalId (string) --

        Value returned by a call to CreateEndpoint that can be used for cross-account validation. Use it on a subsequent call to CreateEndpoint to create the endpoint with a cross-account.

      • DynamoDbSettings (dict) --

        The settings for the DynamoDB target endpoint. For more information, see the DynamoDBSettings structure.

        • ServiceAccessRoleArn (string) --

          The Amazon Resource Name (ARN) used by the service to access the IAM role. The role must allow the iam:PassRole action.

      • S3Settings (dict) --

        The settings for the S3 target endpoint. For more information, see the S3Settings structure.

        • ServiceAccessRoleArn (string) --

          The Amazon Resource Name (ARN) used by the service to access the IAM role. The role must allow the iam:PassRole action. It is a required parameter that enables DMS to write and read objects from an S3 bucket.

        • ExternalTableDefinition (string) --

          Specifies how tables are defined in the S3 source files only.

        • CsvRowDelimiter (string) --

          The delimiter used to separate rows in the .csv file for both source and target. The default is a carriage return (\n ).

        • CsvDelimiter (string) --

          The delimiter used to separate columns in the .csv file for both source and target. The default is a comma.

        • BucketFolder (string) --

          An optional parameter to set a folder name in the S3 bucket. If provided, tables are created in the path `` bucketFolder /schema_name /table_name /`` . If this parameter isn't specified, then the path used is `` schema_name /table_name /`` .

        • BucketName (string) --

          The name of the S3 bucket.

        • CompressionType (string) --

          An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Either set this parameter to NONE (the default) or don't use it to leave the files uncompressed. This parameter applies to both .csv and .parquet file formats.

        • EncryptionMode (string) --

          The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS .

          Note

          For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3 . But you can’t change the existing value from SSE_S3 to SSE_KMS .

          To use SSE_S3 , you need an Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:

          • s3:CreateBucket
          • s3:ListBucket
          • s3:DeleteBucket
          • s3:GetBucketLocation
          • s3:GetObject
          • s3:PutObject
          • s3:DeleteObject
          • s3:GetObjectVersion
          • s3:GetBucketPolicy
          • s3:PutBucketPolicy
          • s3:DeleteBucketPolicy
        • ServerSideEncryptionKmsKeyId (string) --

          If you are using SSE_KMS for the EncryptionMode , provide the KMS key ID. The key that you use needs an attached policy that enables Identity and Access Management (IAM) user permissions and allows use of the key.

          Here is a CLI example: ``aws dms create-endpoint --endpoint-identifier value --endpoint-type target --engine-name s3 --s3-settings ServiceAccessRoleArn=*value* ,BucketFolder=*value* ,BucketName=*value* ,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=*value* ``

        • DataFormat (string) --

          The format of the data that you want to use for output. You can choose one of the following:

          • csv : This is a row-based file format with comma-separated values (.csv).
          • parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.
        • EncodingType (string) --

          The type of encoding you are using:

          • RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
          • PLAIN doesn't use encoding at all. Values are stored as they are.
          • PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.
        • DictPageSizeLimit (integer) --

          The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN . This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.

        • RowGroupLength (integer) --

          The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.

          If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).

        • DataPageSize (integer) --

          The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.

        • ParquetVersion (string) --

          The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0 .

        • EnableStatistics (boolean) --

          A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL , DISTINCT , MAX , and MIN values. This parameter defaults to true . This value is used for .parquet file format only.

        • IncludeOpForFullLoad (boolean) --

          A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.

          Note

          DMS supports the IncludeOpForFullLoad parameter in versions 3.1.4 and later.

          For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y , the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.

          Note

          This setting works together with the CdcInsertsOnly and the CdcInsertsAndUpdates parameters for output to .csv files only. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide. .

        • CdcInsertsOnly (boolean) --

          A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.

          If CdcInsertsOnly is set to true or y , only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad . If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false , every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide. .

          Note

          DMS supports the interaction described preceding between the CdcInsertsOnly and IncludeOpForFullLoad parameters in versions 3.1.4 and later.

          CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.
        • TimestampColumnName (string) --

          A value that when nonblank causes DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.

          Note

          DMS supports the TimestampColumnName parameter in versions 3.1.4 and later.

          DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.

          For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.

          For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.

          The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS . By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.

          When the AddColumnName parameter is set to true , DMS also includes a name for the timestamp column that you set with TimestampColumnName .

        • ParquetTimestampInMillisecond (boolean) --

          A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.

          Note

          DMS supports the ParquetTimestampInMillisecond parameter in versions 3.1.4 and later.

          When ParquetTimestampInMillisecond is set to true or y , DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.

          Currently, Amazon Athena and Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or Glue.

          Note

          DMS writes any TIMESTAMP column values written to an S3 file in .csv format with microsecond precision.

          Setting ParquetTimestampInMillisecond has no effect on the string format of the timestamp column value that is inserted by setting the TimestampColumnName parameter.

        • CdcInsertsAndUpdates (boolean) --

          A value that enables a change data capture (CDC) load to write INSERT and UPDATE operations to .csv or .parquet (columnar storage) output files. The default setting is false , but when CdcInsertsAndUpdates is set to true or y , only INSERTs and UPDATEs from the source database are migrated to the .csv or .parquet file.

          For .csv file format only, how these INSERTs and UPDATEs are recorded depends on the value of the IncludeOpForFullLoad parameter. If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to either I or U to indicate INSERT and UPDATE operations at the source. But if IncludeOpForFullLoad is set to false , CDC records are written without an indication of INSERT or UPDATE operations at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide. .

          Note

          DMS supports the use of the CdcInsertsAndUpdates parameter in versions 3.3.1 and later.

          CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.
        • DatePartitionEnabled (boolean) --

          When set to true , this parameter partitions S3 bucket folders based on transaction commit dates. The default value is false . For more information about date-based folder partitioning, see Using date-based folder partitioning .

        • DatePartitionDelimiter (string) --

          Specifies a date separating delimiter to use during folder partitioning. The default value is SLASH . Use this parameter when DatePartitionedEnabled is set to true .

        • UseCsvNoSupValue (boolean) --

          This setting applies if the S3 output files during a change data capture (CDC) load are written in .csv format. If set to true for columns not included in the supplemental log, DMS uses the value specified by ` CsvNoSupValue https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-CsvNoSupValue`__ . If not set or set to false , DMS uses the null value for these columns.

          Note

          This setting is supported in DMS versions 3.4.1 and later.

        • CsvNoSupValue (string) --

          This setting only applies if your Amazon S3 output files during a change data capture (CDC) load are written in .csv format. If ` UseCsvNoSupValue https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-UseCsvNoSupValue`__ is set to true, specify a string value that you want DMS to use for all columns not included in the supplemental log. If you do not specify a string value, DMS uses the null value for these columns regardless of the UseCsvNoSupValue setting.

          Note

          This setting is supported in DMS versions 3.4.1 and later.

        • PreserveTransactions (boolean) --

          If set to true , DMS saves the transaction order for a change data capture (CDC) load on the Amazon S3 target specified by ` CdcPath https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-CdcPath`__ . For more information, see Capturing data changes (CDC) including transaction order on the S3 target .

          Note

          This setting is supported in DMS versions 3.4.2 and later.

        • CdcPath (string) --

          Specifies the folder path of CDC files. For an S3 source, this setting is required if a task captures change data; otherwise, it's optional. If CdcPath is set, DMS reads CDC files from this path and replicates the data changes to the target endpoint. For an S3 target if you set ` PreserveTransactions https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-PreserveTransactions`__ to true , DMS verifies that you have set this parameter to a folder path on your S3 target where DMS can save the transaction order for the CDC load. DMS creates this CDC folder path in either your S3 target working directory or the S3 target location specified by ` BucketFolder https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-BucketFolder`__ and ` BucketName https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-BucketName`__ .

          For example, if you specify CdcPath as MyChangedData , and you specify BucketName as MyTargetBucket but do not specify BucketFolder , DMS creates the CDC folder path following: MyTargetBucket/MyChangedData .

          If you specify the same CdcPath , and you specify BucketName as MyTargetBucket and BucketFolder as MyTargetData , DMS creates the CDC folder path following: MyTargetBucket/MyTargetData/MyChangedData .

          For more information on CDC including transaction order on an S3 target, see Capturing data changes (CDC) including transaction order on the S3 target .

          Note

          This setting is supported in DMS versions 3.4.2 and later.

        • CannedAclForObjects (string) --

          A value that enables DMS to specify a predefined (canned) access control list for objects created in an Amazon S3 bucket as .csv or .parquet files. For more information about Amazon S3 canned ACLs, see Canned ACL in the Amazon S3 Developer Guide.

          The default value is NONE. Valid values include NONE, PRIVATE, PUBLIC_READ, PUBLIC_READ_WRITE, AUTHENTICATED_READ, AWS_EXEC_READ, BUCKET_OWNER_READ, and BUCKET_OWNER_FULL_CONTROL.

        • AddColumnName (boolean) --

        • CdcMaxBatchInterval (integer) --

          Maximum length of the interval, defined in seconds, after which to output a file to Amazon S3.

          When CdcMaxBatchInterval and CdcMinFileSize are both specified, the file write is triggered by whichever parameter condition is met first within an DMS CloudFormation template.

          The default value is 60 seconds.

        • CdcMinFileSize (integer) --

          Minimum file size, defined in megabytes, to reach for a file output to Amazon S3.

          When CdcMinFileSize and CdcMaxBatchInterval are both specified, the file write is triggered by whichever parameter condition is met first within an DMS CloudFormation template.

          The default value is 32 MB.

        • CsvNullValue (string) --

          An optional parameter that specifies how DMS treats null values. While handling the null value, you can use this parameter to pass a user-defined string as null when writing to the target. For example, when target columns are not nullable, you can use this option to differentiate between the empty string value and the null value. So, if you set this parameter value to the empty string ("" or ''), DMS treats the empty string as the null value instead of NULL .

          The default value is NULL . Valid values include any valid string.

        • IgnoreHeaderRows (integer) --

          When this value is set to 1, DMS ignores the first row header in a .csv file. A value of 1 turns on the feature; a value of 0 turns off the feature.

          The default is 0.

        • MaxFileSize (integer) --

          A value that specifies the maximum size (in KB) of any .csv file to be created while migrating to an S3 target during full load.

          The default value is 1,048,576 KB (1 GB). Valid values include 1 to 1,048,576.

        • Rfc4180 (boolean) --

          For an S3 source, when this value is set to true or y , each leading double quotation mark has to be followed by an ending double quotation mark. This formatting complies with RFC 4180. When this value is set to false or n , string literals are copied to the target as is. In this case, a delimiter (row or column) signals the end of the field. Thus, you can't use a delimiter as part of the string, because it signals the end of the value.

          For an S3 target, an optional parameter used to set behavior to comply with RFC 4180 for data migrated to Amazon S3 using .csv file format only. When this value is set to true or y using Amazon S3 as a target, if the data has quotation marks or newline characters in it, DMS encloses the entire column with an additional pair of double quotation marks ("). Every quotation mark within the data is repeated twice.

          The default value is true . Valid values include true , false , y , and n .

If this parameter is left unset (NULL), it defaults to a format of 'YYYY-MM-DD'. Using auto recognizes most strings, even some that aren't supported when you use a date format string.

          If your date and time values use formats different from each other, set this to auto .

        • EmptyAsNull (boolean) --

          A value that specifies whether DMS should migrate empty CHAR and VARCHAR fields as NULL. A value of true sets empty CHAR and VARCHAR fields to null. The default is false .

          When set to true , this value causes a task to fail if the actual size of a LOB column is greater than the specified LobMaxSize .

          If task is set to Limited LOB mode and this option is set to true, the task fails instead of truncating the LOB data.

        • HeartbeatEnable (boolean) --

          The write-ahead log (WAL) heartbeat feature mimics a dummy transaction. By doing this, it prevents idle logical replication slots from holding onto old WAL logs, which can result in storage full situations on the source. This heartbeat keeps restart_lsn moving and prevents storage full scenarios.

        • HeartbeatSchema (string) --

          Sets the schema in which the heartbeat artifacts are created.

        • HeartbeatFrequency (integer) --

          Sets the WAL heartbeat frequency (in minutes).

          For this parameter, provide the code of the script itself, not the name of a file containing the script.

        • CleanSourceMetadataOnMismatch (boolean) --

          Adjusts the behavior of DMS when migrating from an SQL Server source database that is hosted as part of an Always On availability group cluster. If you need DMS to poll all the nodes in the Always On cluster for transaction backups, set this attribute to false .

        • DatabaseName (string) --

          Database name for the endpoint. For a MySQL source or target endpoint, don't explicitly specify the database using the DatabaseName request parameter on either the CreateEndpoint or ModifyEndpoint API call.

          Endpoint connection user name.

        • SecretsManagerAccessRoleArn (string) --

          The full Amazon Resource Name (ARN) of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret . The role must allow the iam:PassRole action. SecretsManagerSecret has the value of the Amazon Web Services Secrets Manager secret that allows access to the MySQL endpoint.

          Note

          You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerSecretId . Or you can specify clear-text values for UserName , Password , ServerName , and Port . You can't specify both. For more information on creating this SecretsManagerSecret and the SecretsManagerAccessRoleArn and SecretsManagerSecretId required to access it, see Using secrets to access Database Migration Service resources in the Database Migration Service User Guide .

        The settings for the Oracle source and target endpoint. For more information, see the OracleSettings structure.

        • AddSupplementalLogging (boolean) --

          Set this attribute to set up table-level supplemental logging for the Oracle database. This attribute enables PRIMARY KEY supplemental logging on all tables selected for a migration task.

          If you use this option, you still need to enable database-level supplemental logging.

        • ArchivedLogDestId (integer) --

          Specifies the ID of the destination for the archived redo logs. This value should be the same as a number in the dest_id column of the v$archived_log view. If you work with an additional redo log destination, use the AdditionalArchivedLogDestId option to specify the additional destination ID. Doing this improves performance by ensuring that the correct logs are accessed from the outset.

        • AdditionalArchivedLogDestId (integer) --

          Set this attribute with ArchivedLogDestId in a primary/ standby setup. This attribute is useful in the case of a switchover. In this case, DMS needs to know which destination to get archive redo logs from to read changes. This need arises because the previous primary instance is now a standby instance after switchover.

          Although DMS supports the use of the Oracle RESETLOGS option to open the database, never use RESETLOGS unless necessary. For additional information about RESETLOGS , see RMAN Data Repair Concepts in the Oracle Database Backup and Recovery User's Guide .

        • ExtraArchivedLogDestIds (list) --

          Specifies the IDs of one more destinations for one or more archived redo logs. These IDs are the values of the dest_id column in the v$archived_log view. Use this setting with the archivedLogDestId extra connection attribute in a primary-to-single setup or a primary-to-multiple-standby setup.

          This setting is useful in a switchover when you use an Oracle Data Guard database as a source. In this case, DMS needs information about what destination to get archive redo logs from to read changes. DMS needs this because after the switchover the previous primary is a standby instance. For example, in a primary-to-single standby setup you might apply the following settings.

          archivedLogDestId=1; ExtraArchivedLogDestIds=[2]

          In a primary-to-multiple-standby setup, you might apply the following settings.

          archivedLogDestId=1; ExtraArchivedLogDestIds=[2,3,4]

          Although DMS supports the use of the Oracle RESETLOGS option to open the database, never use RESETLOGS unless it's necessary. For more information about RESETLOGS , see RMAN Data Repair Concepts in the Oracle Database Backup and Recovery User's Guide .

        • ReadBackupOnly (boolean) --

          When this attribute is set to Y , DMS only reads changes from transaction log backups and doesn't read from the active transaction log file during ongoing replication. Setting this parameter to Y enables you to control active transaction log file growth during full load and ongoing replication tasks. However, it can add some source latency to ongoing replication.

        • SafeguardPolicy (string) --

          Use this attribute to minimize the need to access the backup log and enable DMS to prevent truncation using one of the following two methods.

          Start transactions in the database: This is the default method. When this method is used, DMS prevents TLOG truncation by mimicking a transaction in the database. As long as such a transaction is open, changes that appear after the transaction started aren't truncated. If you need Microsoft Replication to be enabled in your database, then you must choose this method.

          Exclusively use sp_repldone within a single task : When this method is used, DMS reads the changes and then uses sp_repldone to mark the TLOG transactions as ready for truncation. Although this method doesn't involve any transactional activities, it can only be used when Microsoft Replication isn't running. Also, when using this method, only one DMS task can access the database at any given time. Therefore, if you need to run parallel DMS tasks against the same database, use the default method.

          Use this to attribute to transfer data for full-load operations using BCP. When the target table contains an identity column that does not exist in the source table, you must disable the use BCP for loading table option.

        • UseThirdPartyBackupDevice (boolean) --

          When this attribute is set to Y , DMS processes third-party transaction log backups if they are created in native format.

        • SecretsManagerAccessRoleArn (string) --

          The full Amazon Resource Name (ARN) of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret .

        Note

        ` StartReplicationTaskAssessmentRun https://docs.aws.amazon.com/dms/latest/APIReference/API_StartReplicationTaskAssessmentRun.html`__ is an improved premigration task assessment operation. The ` StartReplicationTaskAssessment https://docs.aws.amazon.com/dms/latest/APIReference/API_StartReplicationTaskAssessment.html`__ operation assesses data type compatibility only between the source and target database of a given migration task. In contrast, ` StartReplicationTaskAssessmentRun https://docs.aws.amazon.com/dms/latest/APIReference/API_StartReplicationTaskAssessmentRun.html`__ enables you to specify a variety of premigration task assessments in addition to data type compatibility. These assessments include ones for the validity of primary key definitions and likely issues with database migration performance, among others.

describe_applicable_individual_assessments(**kwargs)

Provides a list of individual assessments that you can specify for a new premigration assessment run, given one or more parameters.

If you specify an existing migration task, this operation provides the default individual assessments you can specify for that task. Otherwise, the specified parameters model elements of a possible migration task on which to base a premigration assessment run.

To use these migration task modeling parameters, you must specify an existing replication instance, a source database engine, a target database engine, and a migration type. This combination of parameters potentially limits the default individual assessments available for an assessment run created for a corresponding migration task.

If you specify no parameters, this operation provides a list of all possible individual assessments that you can specify for an assessment run. If you specify any one of the task modeling parameters, you must specify all of them or the operation cannot provide a list of individual assessments. The only parameter that you can specify alone is for an existing migration task. The specified task definition then determines the default list of individual assessments that you can specify in an assessment run for the task.

    • Endpoints (list) --

      Endpoint description.

      • (dict) --

        Describes an endpoint of a database instance in response to operations such as the following:

        • CreateEndpoint
        • DescribeEndpoint
        • ModifyEndpoint
        • EndpointIdentifier (string) --

          The database endpoint identifier. Identifiers must begin with a letter and must contain only ASCII letters, digits, and hyphens. They can't end with a hyphen or contain two consecutive hyphens.

        • S3Settings (dict) --

          The settings for the S3 target endpoint. For more information, see the S3Settings structure.

          • ServiceAccessRoleArn (string) --

            The Amazon Resource Name (ARN) used by the service to access the IAM role. The role must allow the iam:PassRole action. It is a required parameter that enables DMS to write and read objects from an S3 bucket.

          • ExternalTableDefinition (string) --

            Specifies how tables are defined in the S3 source files only.

          • CsvRowDelimiter (string) --

          • BucketFolder (string) --

            An optional parameter to set a folder name in the S3 bucket. If provided, tables are created in the path `` bucketFolder /schema_name /table_name /`` . If this parameter isn't specified, then the path used is `` schema_name /table_name /`` .

          • BucketName (string) --

            The name of the S3 bucket.

          • CompressionType (string) --

            An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Either set this parameter to NONE (the default) or don't use it to leave the files uncompressed. This parameter applies to both .csv and .parquet file formats.

          • EncryptionMode (string) --

            The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS .

            Note

            For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3 . But you can’t change the existing value from SSE_S3 to SSE_KMS .

            To use SSE_S3 , you need an Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:

            • s3:CreateBucket
            • s3:ListBucket
            • s3:DeleteBucket
            • s3:GetBucketLocation
            • s3:GetObject
            • s3:PutObject
            • s3:DeleteObject
            • s3:GetObjectVersion
            • s3:GetBucketPolicy
            • s3:PutBucketPolicy
            • s3:DeleteBucketPolicy
          • ServerSideEncryptionKmsKeyId (string) --

            If you are using SSE_KMS for the EncryptionMode , provide the KMS key ID. The key that you use needs an attached policy that enables Identity and Access Management (IAM) user permissions and allows use of the key.

            Here is a CLI example: ``aws dms create-endpoint --endpoint-identifier value --endpoint-type target --engine-name s3 --s3-settings ServiceAccessRoleArn=*value* ,BucketFolder=*value* ,BucketName=*value* ,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=*value* ``

          • DataFormat (string) --

            The format of the data that you want to use for output. You can choose one of the following:

            • csv : This is a row-based file format with comma-separated values (.csv).
            • parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.
          • EncodingType (string) --

            The type of encoding you are using:

            • RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
            • PLAIN doesn't use encoding at all. Values are stored as they are.
            • PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.
          • DictPageSizeLimit (integer) --

            The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN . This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.

          • RowGroupLength (integer) --

            The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.

            If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).

          • DataPageSize (integer) --

            The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.

          • ParquetVersion (string) --

            The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0 .

          • EnableStatistics (boolean) --

            A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL , DISTINCT , MAX , and MIN values. This parameter defaults to true . This value is used for .parquet file format only.

          • IncludeOpForFullLoad (boolean) --

            A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.

            Note

            DMS supports the IncludeOpForFullLoad parameter in versions 3.1.4 and later.

            For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y , the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.

            Note

            This setting works together with the CdcInsertsOnly and the CdcInsertsAndUpdates parameters for output to .csv files only. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide. .

          • CdcInsertsOnly (boolean) --

            A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.

            If CdcInsertsOnly is set to true or y , only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad . If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false , every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide. .

            Note

            DMS supports the interaction described preceding between the CdcInsertsOnly and IncludeOpForFullLoad parameters in versions 3.1.4 and later.

            CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.

          • TimestampColumnName (string) --

            A value that when nonblank causes DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.

            Note

            DMS supports the TimestampColumnName parameter in versions 3.1.4 and later.

            DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.

            For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.

            For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.

            The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS . By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.

            When the AddColumnName parameter is set to true , DMS also includes a name for the timestamp column that you set with TimestampColumnName .

          • ParquetTimestampInMillisecond (boolean) --

            A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.

            Note

            DMS supports the ParquetTimestampInMillisecond parameter in versions 3.1.4 and later.

            When ParquetTimestampInMillisecond is set to true or y , DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.

            Currently, Amazon Athena and Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or Glue.

            Note

            DMS writes any TIMESTAMP column values written to an S3 file in .csv format with microsecond precision.

            Setting ParquetTimestampInMillisecond has no effect on the string format of the timestamp column value that is inserted by setting the TimestampColumnName parameter.

          • CdcInsertsAndUpdates (boolean) --

            A value that enables a change data capture (CDC) load to write INSERT and UPDATE operations to .csv or .parquet (columnar storage) output files. The default setting is false , but when CdcInsertsAndUpdates is set to true or y , only INSERTs and UPDATEs from the source database are migrated to the .csv or .parquet file.

            For .csv file format only, how these INSERTs and UPDATEs are recorded depends on the value of the IncludeOpForFullLoad parameter. If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to either I or U to indicate INSERT and UPDATE operations at the source. But if IncludeOpForFullLoad is set to false , CDC records are written without an indication of INSERT or UPDATE operations at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide. .

            Note

            DMS supports the use of the CdcInsertsAndUpdates parameter in versions 3.3.1 and later.

            CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.

          • DatePartitionEnabled (boolean) --

            When set to true , this parameter partitions S3 bucket folders based on transaction commit dates. The default value is false . For more information about date-based folder partitioning, see Using date-based folder partitioning .

          • DatePartitionSequence (string) --

            Identifies the sequence of the date format to use during folder partitioning. The default value is YYYYMMDD . Use this parameter when DatePartitionedEnabled is set to true .

          • DatePartitionDelimiter (string) --

            Specifies a date separating delimiter to use during folder partitioning. The default value is SLASH . Use this parameter when DatePartitionedEnabled is set to true .

          • UseCsvNoSupValue (boolean) --

            This setting applies if the S3 output files during a change data capture (CDC) load are written in .csv format. If set to true for columns not included in the supplemental log, DMS uses the value specified by ` CsvNoSupValue https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-CsvNoSupValue`__ . If not set or set to false , DMS uses the null value for these columns.

            Note

            This setting is supported in DMS versions 3.4.1 and later.

          • CsvNoSupValue (string) --

            This setting only applies if your Amazon S3 output files during a change data capture (CDC) load are written in .csv format. If ` UseCsvNoSupValue https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-UseCsvNoSupValue`__ is set to true, specify a string value that you want DMS to use for all columns not included in the supplemental log. If you do not specify a string value, DMS uses the null value for these columns regardless of the UseCsvNoSupValue setting.

            Note

            This setting is supported in DMS versions 3.4.1 and later.

          • PreserveTransactions (boolean) --

            If set to true , DMS saves the transaction order for a change data capture (CDC) load on the Amazon S3 target specified by ` CdcPath https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-CdcPath`__ . For more information, see Capturing data changes (CDC) including transaction order on the S3 target .

            Note

            This setting is supported in DMS versions 3.4.2 and later.

          • CdcPath (string) --

            Specifies the folder path of CDC files. For an S3 source, this setting is required if a task captures change data; otherwise, it's optional. If CdcPath is set, DMS reads CDC files from this path and replicates the data changes to the target endpoint. For an S3 target if you set ` PreserveTransactions https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-PreserveTransactions`__ to true , DMS verifies that you have set this parameter to a folder path on your S3 target where DMS can save the transaction order for the CDC load. DMS creates this CDC folder path in either your S3 target working directory or the S3 target location specified by ` BucketFolder https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-BucketFolder`__ and ` BucketName https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-BucketName`__ .

            For example, if you specify CdcPath as MyChangedData , and you specify BucketName as MyTargetBucket but do not specify BucketFolder , DMS creates the CDC folder path following: MyTargetBucket/MyChangedData .

            If you specify the same CdcPath , and you specify BucketName as MyTargetBucket and BucketFolder as MyTargetData , DMS creates the CDC folder path following: MyTargetBucket/MyTargetData/MyChangedData .

            For more information on CDC including transaction order on an S3 target, see Capturing data changes (CDC) including transaction order on the S3 target .

            Note

            This setting is supported in DMS versions 3.4.2 and later.

          • CannedAclForObjects (string) --

            A value that enables DMS to specify a predefined (canned) access control list for objects created in an Amazon S3 bucket as .csv or .parquet files. For more information about Amazon S3 canned ACLs, see Canned ACL in the Amazon S3 Developer Guide.

            The default value is NONE. Valid values include NONE, PRIVATE, PUBLIC_READ, PUBLIC_READ_WRITE, AUTHENTICATED_READ, AWS_EXEC_READ, BUCKET_OWNER_READ, and BUCKET_OWNER_FULL_CONTROL.

          • AddColumnName (boolean) --

            An optional parameter that, when set to true or y , you can use to add column name information to the .csv output file.

            The default value is false . Valid values are true , false , y , and n .

          • CdcMaxBatchInterval (integer) --

            Maximum length of the interval, defined in seconds, after which to output a file to Amazon S3.

            When CdcMaxBatchInterval and CdcMinFileSize are both specified, the file write is triggered by whichever parameter condition is met first within an DMS CloudFormation template.

            The default value is 60 seconds.

          • CdcMinFileSize (integer) --

            Minimum file size, defined in megabytes, to reach for a file output to Amazon S3.

            When CdcMinFileSize and CdcMaxBatchInterval are both specified, the file write is triggered by whichever parameter condition is met first within an DMS CloudFormation template.

            The default value is 32 MB.

          • CsvNullValue (string) --

            An optional parameter that specifies how DMS treats null values. While handling the null value, you can use this parameter to pass a user-defined string as null when writing to the target. For example, when target columns are not nullable, you can use this option to differentiate between the empty string value and the null value. So, if you set this parameter value to the empty string ("" or ''), DMS treats the empty string as the null value instead of NULL .

            The default value is NULL . Valid values include any valid string.

          • IgnoreHeaderRows (integer) --

            When this value is set to 1, DMS ignores the first row header in a .csv file. A value of 1 turns on the feature; a value of 0 turns off the feature.

            The default is 0.

          • MaxFileSize (integer) --

            A value that specifies the maximum size (in KB) of any .csv file to be created while migrating to an S3 target during full load.

            The default value is 1,048,576 KB (1 GB). Valid values include 1 to 1,048,576.

          • Rfc4180 (boolean) --

            For an S3 source, when this value is set to true or y , each leading double quotation mark has to be followed by an ending double quotation mark. This formatting complies with RFC 4180. When this value is set to false or n , string literals are copied to the target as is. In this case, a delimiter (row or column) signals the end of the field. Thus, you can't use a delimiter as part of the string, because it signals the end of the value.

            For an S3 target, an optional parameter used to set behavior to comply with RFC 4180 for data migrated to Amazon S3 using .csv file format only. When this value is set to true or y using Amazon S3 as a target, if the data has quotation marks or newline characters in it, DMS encloses the entire column with an additional pair of double quotation marks ("). Every quotation mark within the data is repeated twice.

            The default value is true . Valid values include true , false , y , and n .

        • DmsTransferSettings (dict) --

          The settings in JSON format for the DMS transfer type of source endpoint.

          Possible settings include the following:

          • SecretsManagerAccessRoleArn (string) --

            The full Amazon Resource Name (ARN) of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret . The role must allow the iam:PassRole action. SecretsManagerSecret has the value of the Amazon Web Services Secrets Manager secret that allows access to the MongoDB endpoint.

            Note

            You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerSecretId . Or you can specify clear-text values for UserName , Password , ServerName , and Port . You can't specify both. For more information on creating this SecretsManagerSecret and the SecretsManagerAccessRoleArn and SecretsManagerSecretId required to access it, see Using secrets to access Database Migration Service resources in the Database Migration Service User Guide .

          • SecretsManagerSecretId (string) --

          • ServiceAccessRoleArn (string) --

            The Amazon Resource Name (ARN) for the IAM role that DMS uses to write to the Kinesis data stream. The role must allow the iam:PassRole action.

          • IncludeTransactionDetails (boolean) --

            Provides detailed transaction information from the source database. This information includes a commit timestamp, a log position, and values for transaction_id , previous transaction_id , and transaction_record_id (the record offset within a transaction). The default is false .

          • IncludePartitionValue (boolean) --

            Shows the partition value within the Kinesis message output, unless the partition type is schema-table-type . The default is false .

          • PartitionIncludeSchemaTable (boolean) --

            Prefixes schema and table names to partition values, when the partition type is primary-key-type . Doing this increases data distribution among Kinesis shards. For example, suppose that a SysBench schema has thousands of tables and each table has only limited range for a primary key. In this case, the same primary key is sent from thousands of tables to the same shard, which causes throttling. The default is false .

          • IncludeTableAlterOperations (boolean) --

            Includes any data definition language (DDL) operations that change the table in the control data, such as rename-table , drop-table , add-column , drop-column , and rename-column . The default is false .

          • NoHexPrefix (boolean) --

            Set this optional parameter to true to avoid adding a '0x' prefix to raw data in hexadecimal format. For example, by default, DMS adds a '0x' prefix to the LOB column type in hexadecimal format moving from an Oracle source to an Amazon Kinesis target. Use the NoHexPrefix endpoint setting to enable migration of RAW data type columns without adding the '0x' prefix.

        • KafkaSettings (dict) --

          The settings for the Apache Kafka target endpoint. For more information, see the KafkaSettings structure.

          • Broker (string) --

          • PartitionIncludeSchemaTable (boolean) --

            Prefixes schema and table names to partition values, when the partition type is primary-key-type . Doing this increases data distribution among Kafka partitions. For example, suppose that a SysBench schema has thousands of tables and each table has only limited range for a primary key. In this case, the same primary key is sent from thousands of tables to the same partition, which causes throttling. The default is false .

          • IncludeTableAlterOperations (boolean) --

            Includes any data definition language (DDL) operations that change the table in the control data, such as rename-table , drop-table , add-column , drop-column , and rename-column . The default is false .

          • IncludeControlDetails (boolean) --

          • SaslUsername (string) --

            The secure user name you created when you first set up your MSK cluster to validate a client identity and make an encrypted connection between server and client using SASL-SSL authentication.

          • SaslPassword (string) --

            The secure password you created when you first set up your MSK cluster to validate a client identity and make an encrypted connection between server and client using SASL-SSL authentication.

          • NoHexPrefix (boolean) --

            Set this optional parameter to true to avoid adding a '0x' prefix to raw data in hexadecimal format. For example, by default, DMS adds a '0x' prefix to the LOB column type in hexadecimal format moving from an Oracle source to a Kafka target. Use the NoHexPrefix endpoint setting to enable migration of RAW data type columns without adding the '0x' prefix.

        • ElasticsearchSettings (dict) --

          The settings for the Elasticsearch source endpoint. For more information, see the ElasticsearchSettings structure.

          • ServiceAccessRoleArn (string) --

            The Amazon Resource Name (ARN) used by the service to access the IAM role. The role must allow the iam:PassRole action.

          • EndpointUri (string) --

            The endpoint for the Elasticsearch cluster. DMS uses HTTPS if a transport protocol (http/https) is not specified.

          • FullLoadErrorPercentage (integer) --

            The maximum percentage of records that can fail to be written before a full load operation stops.

            To avoid early failure, this counter is only effective after 1000 records are transferred. Elasticsearch also has the concept of error monitoring during the last 10 minutes of an Observation Window. If transfer of all records fail in the last 10 minutes, the full load operation stops.

          • ErrorRetryDuration (integer) --

            The maximum number of seconds for which DMS retries failed API requests to the Elasticsearch cluster.

        • NeptuneSettings (dict) --

            This parameter applies only to TIMESTAMP and DATE columns. Always use ACCEPTANYDATE with the DATEFORMAT parameter. If the date format for the data doesn't match the DATEFORMAT specification, Amazon Redshift inserts a NULL value into that field.

          • AfterConnectScript (string) --

            Code to run after connecting. This parameter should contain the code itself, not the name of a file containing the code.

          • BucketFolder (string) --

            An S3 folder where the comma-separated-value (.csv) files are stored before being uploaded to the target Redshift cluster.

            For full load mode, DMS converts source records into .csv files and loads them to the BucketFolder/TableID path. DMS uses the Redshift COPY command to upload the .csv files to the target table. The files are deleted once the COPY operation has finished. For more information, see COPY in the Amazon Redshift Database Developer Guide .

            Note

            For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3 . But you can’t change the existing value from SSE_S3 to SSE_KMS .

            To use SSE_S3 , create an Identity and Access Management (IAM) role with a policy that allows "arn:aws:s3:::*" to use the following actions: "s3:PutObject", "s3:ListBucket"

          • ExplicitIds (boolean) --

            This setting is only valid for a full-load migration task. Set ExplicitIds to true to have tables with IDENTITY columns override their auto-generated values with explicit values loaded from the source data files used to populate the tables. The default is false .

          • FileTransferUploadStreams (integer) --

            The number of threads used to upload a single file. This parameter accepts a value from 1 through 64. It defaults to 10.

          • WriteBufferSize (integer) --

            The size (in KB) of the in-memory file write buffer used when generating .csv files on the local disk at the DMS replication instance. The default value is 1000 (buffer size is 1000KB).

          • SecretsManagerAccessRoleArn (string) --

            The full Amazon Resource Name (ARN) of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret . The role must allow the iam:PassRole action. SecretsManagerSecret has the value of the Amazon Web Services Secrets Manager secret that allows access to the Amazon Redshift endpoint.

            Note

            You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerSecretId . Or you can specify clear-text values for UserName , Password , ServerName , and Port . You can't specify both.

          • AfterConnectScript (string) --

            For use with change data capture (CDC) only, this attribute has DMS bypass foreign keys and user triggers to reduce the time it takes to bulk load data.

            Example: afterConnectScript=SET session_replication_role='replica'

          • CaptureDdls (boolean) --

            To capture DDL events, DMS creates various artifacts in the PostgreSQL database when the task starts. You can later remove these artifacts.

            If this value is set to N , you don't have to create tables or triggers on the source database.

          • MaxFileSize (integer) --

            Specifies the maximum size (in KB) of any .csv file used to transfer data to PostgreSQL.

            Example: maxFileSize=512

            Example: executeTimeout=100;

          • FailTasksOnLobTruncation (boolean) --

            When set to true , this value causes a task to fail if the actual size of a LOB column is greater than the specified LobMaxSize .

            If task is set to Limited LOB mode and this option is set to true, the task fails instead of truncating the LOB data.

          • HeartbeatEnable (boolean) --

            The write-ahead log (WAL) heartbeat feature mimics a dummy transaction. By doing this, it prevents idle logical replication slots from holding onto old WAL logs, which can result in storage full situations on the source. This heartbeat keeps restart_lsn moving and prevents storage full scenarios.

          • HeartbeatSchema (string) --

            Sets the schema in which the heartbeat artifacts are created.

          • HeartbeatFrequency (integer) --

            Sets the name of a previously created logical replication slot for a change data capture (CDC) load of the PostgreSQL source instance.

            When used with the CdcStartPosition request parameter for the DMS API , this attribute also makes it possible to use native CDC start points. DMS verifies that the specified logical replication slot exists before starting the CDC load task. It also verifies that the task was created with a valid setting of CdcStartPosition . If the specified slot doesn't exist or the task doesn't have a valid CdcStartPosition setting, DMS raises an error.

            For more information about setting the CdcStartPosition request parameter, see Determining a CDC native start point in the Database Migration Service User Guide . For more information about using CdcStartPosition , see CreateReplicationTask , StartReplicationTask , and ModifyReplicationTask .

          • PluginName (string) --

            Specifies the plugin to use to create a replication slot.

          • SecretsManagerAccessRoleArn (string) --

            The full Amazon Resource Name (ARN) of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret . The role must allow the iam:PassRole action. SecretsManagerSecret has the value of the Amazon Web Services Secrets Manager secret that allows access to the PostgreSQL endpoint.

            Note

            You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerSecretId . Or you can specify clear-text values for UserName , Password , ServerName , and Port . You can't specify both. For more information on creating this SecretsManagerSecret and the SecretsManagerAccessRoleArn and SecretsManagerSecretId required to access it, see Using secrets to access Database Migration Service resources in the Database Migration Service User Guide .

            For this parameter, provide the code of the script itself, not the name of a file containing the script.

          • CleanSourceMetadataOnMismatch (boolean) --

            Adjusts the behavior of DMS when migrating from an SQL Server source database that is hosted as part of an Always On availability group cluster. If you need DMS to poll all the nodes in the Always On cluster for transaction backups, set this attribute to false .

          • DatabaseName (string) --

            Database name for the endpoint. For a MySQL source or target endpoint, don't explicitly specify the database using the DatabaseName request parameter on either the CreateEndpoint or ModifyEndpoint API call. Specifying DatabaseName when you create or modify a MySQL endpoint replicates all the task tables to this single database. For MySQL endpoints, you specify the database only when you specify the schema in the table-mapping rules of the DMS task.

          • EventsPollInterval (integer) --

            Specifies how often to check the binary log for new changes/events when the database is idle.

            Note

            You can specify one of two sets of values for these permissions. You can specify the values for this setting and SecretsManagerSecretId . Or you can specify clear-text values for UserName , Password , ServerName , and Port . You can't specify both. For more information on creating this SecretsManagerSecret and the SecretsManagerAccessRoleArn and SecretsManagerSecretId required to access it, see Using secrets to access Database Migration Service resources in the Database Migration Service User Guide .

          • SecretsManagerSecretId (string) --

            The full ARN, partial ARN, or friendly name of the SecretsManagerSecret that contains the MySQL endpoint connection details.

        • OracleSettings (dict) --

          The settings for the Oracle source and target endpoint. For more information, see the OracleSettings structure.

          • AddSupplementalLogging (boolean) --

            Set this attribute to set up table-level supplemental logging for the Oracle database. This attribute enables PRIMARY KEY supplemental logging on all tables selected for a migration task.

            If you use this option, you still need to enable database-level supplemental logging.

          • ArchivedLogDestId (integer) --

            Specifies the ID of the destination for the archived redo logs. This value should be the same as a number in the dest_id column of the v$archived_log view. If you work with an additional redo log destination, use the AdditionalArchivedLogDestId option to specify the additional destination ID. Doing this improves performance by ensuring that the correct logs are accessed from the outset.

          • AdditionalArchivedLogDestId (integer) --

            Set this attribute with ArchivedLogDestId in a primary/ standby setup. This attribute is useful in the case of a switchover. In this case, DMS needs to know which destination to get archive redo logs from to read changes. This need arises because the previous primary instance is now a standby instance after switchover.

            Although DMS supports the use of the Oracle RESETLOGS option to open the database, never use RESETLOGS unless necessary. For additional information about RESETLOGS , see RMAN Data Repair Concepts in the Oracle Database Backup and Recovery User's Guide .

          • ExtraArchivedLogDestIds (list) --

            Specifies the IDs of one more destinations for one or more archived redo logs. These IDs are the values of the dest_id column in the v$archived_log view. Use this setting with the archivedLogDestId extra connection attribute in a primary-to-single setup or a primary-to-multiple-standby setup.

            This setting is useful in a switchover when you use an Oracle Data Guard database as a source. In this case, DMS needs information about what destination to get archive redo logs from to read changes. DMS needs this because after the switchover the previous primary is a standby instance. For example, in a primary-to-single standby setup you might apply the following settings.

            archivedLogDestId=1; ExtraArchivedLogDestIds=[2]

            In a primary-to-multiple-standby setup, you might apply the following settings.

            archivedLogDestId=1; ExtraArchivedLogDestIds=[2,3,4]

            Although DMS supports the use of the Oracle RESETLOGS option to open the database, never use RESETLOGS unless it's necessary. For more information about RESETLOGS , see RMAN Data Repair Concepts in the Oracle Database Backup and Recovery User's Guide .

            Cleans and recreates table metadata information on the replication instance when a mismatch occurs. An example is a situation where running an alter DDL statement on a table might result in different information about the table cached in the replication instance.

          • ReadBackupOnly (boolean) --

            When this attribute is set to Y , DMS only reads changes from transaction log backups and doesn't read from the active transaction log file during ongoing replication. Setting this parameter to Y enables you to control active transaction log file growth during full load and ongoing replication tasks. However, it can add some source latency to ongoing replication.

          • SafeguardPolicy (string) --

            Use this attribute to minimize the need to access the backup log and enable DMS to prevent truncation using one of the following two methods.

            Start transactions in the database: This is the default method. When this method is used, DMS prevents TLOG truncation by mimicking a transaction in the database. As long as such a transaction is open, changes that appear after the transaction started aren't truncated. If you need Microsoft Replication to be enabled in your database, then you must choose this method.

            Exclusively use sp_repldone within a single task : When this method is used, DMS reads the changes and then uses sp_repldone to mark the TLOG transactions as ready for truncation. Although this method doesn't involve any transactional activities, it can only be used when Microsoft Replication isn't running. Also, when using this method, only one DMS task can access the database at any given time. Therefore, if you need to run parallel DMS tasks against the same database, use the default method.

          • ServerName (string) --

          • UseThirdPartyBackupDevice (boolean) --

            When this attribute is set to Y , DMS processes third-party transaction log backups if they are created in native format.

          • SecretsManagerAccessRoleArn (string) --

            The full Amazon Resource Name (ARN) of the IAM role that specifies DMS as the trusted entity and grants the required permissions to access the value in SecretsManagerSecret .
