Athena.Client¶A low-level client representing Amazon Athena
Amazon Athena is an interactive query service that lets you use standard SQL to analyze data directly in Amazon S3. You can point Athena at your data in Amazon S3 and run ad-hoc queries and get results in seconds. Athena is serverless, so there is no infrastructure to set up or manage. You pay only for the queries you run. Athena scales automatically—executing queries in parallel—so results are fast, even with large datasets and complex queries. For more information, see What is Amazon Athena in the Amazon Athena User Guide .
If you connect to Athena using the JDBC driver, use version 1.1.0 of the driver or later with the Amazon Athena API. Earlier version drivers do not support the API. For more information and to download the driver, see Accessing Amazon Athena with JDBC .
For code samples using the Amazon Web Services SDK for Java, see Examples and Code Samples in the Amazon Athena User Guide .

Response Structure
Information about a query execution.
Information about a single instance of a query execution.
The unique identifier for each query execution.
The SQL query statements which the query execution ran.
The type of query statement that was run. DDL indicates DDL query statements. DML indicates DML (Data Manipulation Language) query statements, such as CREATE TABLE AS SELECT . UTILITY indicates query statements other than DDL and DML, such as SHOW CREATE TABLE , or DESCRIBE TABLE .
The location in Amazon S3 where query results were stored and the encryption option, if any, used for query results. These are known as "client-side settings". If workgroup settings override client-side settings, then the query uses the location for the query results and the encryption configuration that are specified for the workgroup.
The location in Amazon S3 where your query results are stored, such as s3://path/to/query/bucket/ . To run the query, you must specify the query results location using one of the ways: either for individual queries using either this setting (client-side), or in the workgroup, using WorkGroupConfiguration . If none of them is set, Athena issues an error that no output location is provided. For more information, see Query Results . If workgroup settings override client-side settings, then the query uses the settings specified for the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration .
If query results are encrypted in Amazon S3, indicates the encryption option used (for example, SSE_KMS or CSE_KMS ) and key information. This is a client-side setting. If workgroup settings override client-side settings, then the query uses the encryption configuration that is specified for the workgroup, and also uses the location for storing query results specified in the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration and Workgroup Settings Override Client-Side Settings .
Indicates whether Amazon S3 server-side encryption with Amazon S3-managed keys (SSE_S3 ), server-side encryption with KMS-managed keys (SSE_KMS ), or client-side encryption with KMS-managed keys (CSE_KMS ) is used.
If a query runs in a workgroup and the workgroup overrides client-side settings, then the workgroup's setting for encryption is used. It specifies whether query results must be encrypted, for all queries that run in this workgroup.
For SSE_KMS and CSE_KMS , this is the KMS key ARN or ID.
The Amazon Web Services account ID that you expect to be the owner of the Amazon S3 bucket specified by ResultConfiguration$OutputLocation . If set, Athena uses the value for ExpectedBucketOwner when it makes Amazon S3 calls to your specified output location. If the ExpectedBucketOwner Amazon Web Services account ID does not match the actual owner of the Amazon S3 bucket, the call fails with a permissions error.
This is a client-side setting. If workgroup settings override client-side settings, then the query uses the ExpectedBucketOwner setting that is specified for the workgroup, and also uses the location for storing query results specified in the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration and Workgroup Settings Override Client-Side Settings .
Indicates that an Amazon S3 canned ACL should be set to control ownership of stored query results. Currently the only supported canned ACL is BUCKET_OWNER_FULL_CONTROL . This is a client-side setting. If workgroup settings override client-side settings, then the query uses the ACL configuration that is specified for the workgroup, and also uses the location for storing query results specified in the workgroup. For more information, see WorkGroupConfiguration$EnforceWorkGroupConfiguration and Workgroup Settings Override Client-Side Settings .
The Amazon S3 canned ACL that Athena should specify when storing query results. Currently the only supported canned ACL is BUCKET_OWNER_FULL_CONTROL . If a query runs in a workgroup and the workgroup overrides client-side settings, then the Amazon S3 canned ACL specified in the workgroup's settings is used for all queries that run in the workgroup. For more information about Amazon S3 canned ACLs, see Canned ACL in the Amazon S3 User Guide .
Specifies the query result reuse behavior that was used for the query.
Specifies whether previous query results are reused, and if so, their maximum age.
True if previous query results can be reused when the query is run; otherwise, false. The default is false.
Specifies, in minutes, the maximum age of a previous query result that Athena should consider for reuse. The default is 60.
The database in which the query execution occurred.
The name of the database used in the query execution. The database must exist in the catalog.
The name of the data catalog used in the query execution.
The completion date, current state, submission time, and state change reason (if applicable) for the query execution.
The state of query execution. QUEUED indicates that the query has been submitted to the service, and Athena will execute the query as soon as resources are available. RUNNING indicates that the query is in execution phase. SUCCEEDED indicates that the query completed without errors. FAILED indicates that the query experienced an error and did not complete processing. CANCELLED indicates that a user input interrupted query execution.
Note
Athena automatically retries your queries in cases of certain transient errors. As a result, you may see the query state transition from RUNNING or FAILED to QUEUED .
Further detail about the status of the query.
The date and time that the query was submitted.
The date and time that the query completed.
Provides information about an Athena query error.
An integer value that specifies the category of a query failure error. The following list shows the category for each integer value.
1 - System2 - User
3 - Other
An integer value that provides specific information about an Athena query error. For the meaning of specific values, see the Error Type Reference in the Amazon Athena User Guide .
True if the query might succeed if resubmitted.
Contains a short description of the error that occurred.
Query execution statistics, such as the amount of data scanned, the amount of time that the query took to process, and the type of statement that was run.
The number of milliseconds that the query took to execute.
The number of bytes in the data that was queried.
The location and file name of a data manifest file. The manifest file is saved to the Athena query results location in Amazon S3. The manifest file tracks files that the query wrote to Amazon S3. If the query fails, the manifest file also tracks files that the query intended to write. The manifest is useful for identifying orphaned files resulting from a failed query. For more information, see Working with Query Results, Output Files, and Query History in the Amazon Athena User Guide .
The number of milliseconds that Athena took to run the query.
The number of milliseconds that the query was in your query queue waiting for resources. Note that if transient errors occur, Athena might automatically add the query back to the queue.
The number of milliseconds that Athena took to plan the query processing flow. This includes the time spent retrieving table partitions from the data source. Note that because the query engine performs the query planning, query planning time is a subset of engine processing time.
The number of milliseconds that Athena took to finalize and publish the query results after the query engine finished running the query.
Contains information about whether previous query results were reused for the query.
True if a previous query result was reused; false if the result was generated from a new run of the query.
The name of the workgroup in which the query ran.
The engine version that executed the query.
The engine version requested by the user. Possible values are determined by the output of ListEngineVersions , including Auto. The default is Auto.
Read only. The engine version on which the query runs. If the user requests a valid engine version other than Auto, the effective engine version is the same as the engine version that the user requested. If the user requests Auto, the effective engine version is chosen by Athena. When a request to update the engine version is made by a CreateWorkGroup or UpdateWorkGroup operation, the EffectiveEngineVersion field is ignored.
A list of values for the parameters in a query. The values are applied sequentially to the parameters in the query in the order in which the parameters occur.
Information about the query executions that failed to run.
Describes a query execution that failed to process.
The unique identifier of the query execution.
The error code returned when the query execution failed to process, if applicable.
The error message returned when the query execution failed to process, if applicable.

Response Structure
Information about the query execution.
The unique identifier for each query execution.
The SQL query statements which the query execution ran.
The type of query statement that was run. DDL indicates DDL query statements. DML indicates DML (Data Manipulation Language) query statements, such as CREATE TABLE AS SELECT . UTILITY indicates query statements other than DDL and DML, such as SHOW CREATE TABLE , or DESCRIBE TABLE .
The location in Amazon S3 where query results were stored and the encryption option, if any, used for query results. These are known as "client-side settings". If workgroup settings override client-side settings, then the query uses the location for the query results and the encryption configuration that are specified for the workgroup.
The location in Amazon S3 where your query results are stored, such as s3://path/to/query/bucket/ . To run the query, you must specify the query results location using one of the ways: either for individual queries using either this setting (client-side), or in the workgroup, using WorkGroupConfiguration . If none of them is set, Athena issues an error that no output location is provided. For more information, see Query Results . If workgroup settings override client-side settings, then the query uses the settings specified for the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration .
If query results are encrypted in Amazon S3, indicates the encryption option used (for example, SSE_KMS or CSE_KMS ) and key information. This is a client-side setting. If workgroup settings override client-side settings, then the query uses the encryption configuration that is specified for the workgroup, and also uses the location for storing query results specified in the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration and Workgroup Settings Override Client-Side Settings .
Indicates whether Amazon S3 server-side encryption with Amazon S3-managed keys (SSE_S3 ), server-side encryption with KMS-managed keys (SSE_KMS ), or client-side encryption with KMS-managed keys (CSE_KMS ) is used.
If a query runs in a workgroup and the workgroup overrides client-side settings, then the workgroup's setting for encryption is used. It specifies whether query results must be encrypted, for all queries that run in this workgroup.
For SSE_KMS and CSE_KMS , this is the KMS key ARN or ID.
The Amazon Web Services account ID that you expect to be the owner of the Amazon S3 bucket specified by ResultConfiguration$OutputLocation . If set, Athena uses the value for ExpectedBucketOwner when it makes Amazon S3 calls to your specified output location. If the ExpectedBucketOwner Amazon Web Services account ID does not match the actual owner of the Amazon S3 bucket, the call fails with a permissions error.
This is a client-side setting. If workgroup settings override client-side settings, then the query uses the ExpectedBucketOwner setting that is specified for the workgroup, and also uses the location for storing query results specified in the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration and Workgroup Settings Override Client-Side Settings .
Indicates that an Amazon S3 canned ACL should be set to control ownership of stored query results. Currently the only supported canned ACL is BUCKET_OWNER_FULL_CONTROL . This is a client-side setting. If workgroup settings override client-side settings, then the query uses the ACL configuration that is specified for the workgroup, and also uses the location for storing query results specified in the workgroup. For more information, see WorkGroupConfiguration$EnforceWorkGroupConfiguration and Workgroup Settings Override Client-Side Settings .
The Amazon S3 canned ACL that Athena should specify when storing query results. Currently the only supported canned ACL is BUCKET_OWNER_FULL_CONTROL . If a query runs in a workgroup and the workgroup overrides client-side settings, then the Amazon S3 canned ACL specified in the workgroup's settings is used for all queries that run in the workgroup. For more information about Amazon S3 canned ACLs, see Canned ACL in the Amazon S3 User Guide .
Specifies the query result reuse behavior that was used for the query.
Specifies whether previous query results are reused, and if so, their maximum age.
True if previous query results can be reused when the query is run; otherwise, false. The default is false.
Specifies, in minutes, the maximum age of a previous query result that Athena should consider for reuse. The default is 60.
The database in which the query execution occurred.
The name of the database used in the query execution. The database must exist in the catalog.
The name of the data catalog used in the query execution.
The completion date, current state, submission time, and state change reason (if applicable) for the query execution.
The state of query execution. QUEUED indicates that the query has been submitted to the service, and Athena will execute the query as soon as resources are available. RUNNING indicates that the query is in execution phase. SUCCEEDED indicates that the query completed without errors. FAILED indicates that the query experienced an error and did not complete processing. CANCELLED indicates that a user input interrupted query execution.
Note
Athena automatically retries your queries in cases of certain transient errors. As a result, you may see the query state transition from RUNNING or FAILED to QUEUED .
Further detail about the status of the query.
The date and time that the query was submitted.
The date and time that the query completed.
Provides information about an Athena query error.
An integer value that specifies the category of a query failure error. The following list shows the category for each integer value.
1 - System2 - User
3 - Other
An integer value that provides specific information about an Athena query error. For the meaning of specific values, see the Error Type Reference in the Amazon Athena User Guide .
True if the query might succeed if resubmitted.
Contains a short description of the error that occurred.
Query execution statistics, such as the amount of data scanned, the amount of time that the query took to process, and the type of statement that was run.
The number of milliseconds that the query took to execute.
The number of bytes in the data that was queried.
The location and file name of a data manifest file. The manifest file is saved to the Athena query results location in Amazon S3. The manifest file tracks files that the query wrote to Amazon S3. If the query fails, the manifest file also tracks files that the query intended to write. The manifest is useful for identifying orphaned files resulting from a failed query. For more information, see Working with Query Results, Output Files, and Query History in the Amazon Athena User Guide .
The number of milliseconds that Athena took to run the query.
The number of milliseconds that the query was in your query queue waiting for resources. Note that if transient errors occur, Athena might automatically add the query back to the queue.
The number of milliseconds that Athena took to plan the query processing flow. This includes the time spent retrieving table partitions from the data source. Note that because the query engine performs the query planning, query planning time is a subset of engine processing time.
The number of milliseconds that Athena took to finalize and publish the query results after the query engine finished running the query.
Contains information about whether previous query results were reused for the query.
True if a previous query result was reused; false if the result was generated from a new run of the query.
The name of the workgroup in which the query ran.
The engine version that executed the query.
The engine version requested by the user. Possible values are determined by the output of ListEngineVersions , including Auto. The default is Auto.
Read only. The engine version on which the query runs. If the user requests a valid engine version other than Auto, the effective engine version is the same as the engine version that the user requested. If the user requests Auto, the effective engine version is chosen by Athena. When a request to update the engine version is made by a CreateWorkGroup or UpdateWorkGroup operation, the EffectiveEngineVersion field is ignored.
A list of values for the parameters in a query. The values are applied sequentially to the parameters in the query in the order in which the parameters occur.
Exceptions
Athena.Client.exceptions.InternalServerExceptionAthena.Client.exceptions.InvalidRequestExceptionget_query_results(**kwargs)¶Streams the results of a single query execution specified by QueryExecutionId from the Athena query results location in Amazon S3. For more information, see Query Results in the Amazon Athena User Guide . This request does not execute the query but returns results. Use StartQueryExecution to run a query.
To stream query results successfully, the IAM principal with permission to call GetQueryResults also must have permissions to the Amazon S3 GetObject action for the Athena query results location.
Warning
IAM principals with permission to the Amazon S3 GetObject action for the query results location are able to retrieve query results from Amazon S3 even if permission to the GetQueryResults action is denied. To restrict user or role access, ensure that Amazon S3 permissions to the Athena query location are denied.

Information about the workgroup.
The workgroup name.
The state of the workgroup: ENABLED or DISABLED.
The configuration of the workgroup, which includes the location in Amazon S3 where query results are stored, the encryption configuration, if any, used for query results; whether the Amazon CloudWatch Metrics are enabled for the workgroup; whether workgroup settings override client-side settings; and the data usage limits for the amount of data scanned per query or per workgroup. The workgroup settings override is specified in EnforceWorkGroupConfiguration (true/false) in the WorkGroupConfiguration . See WorkGroupConfiguration$EnforceWorkGroupConfiguration .
The configuration for the workgroup, which includes the location in Amazon S3 where query results are stored and the encryption option, if any, used for query results. To run the query, you must specify the query results location using one of the ways: either in the workgroup using this setting, or for individual queries (client-side), using ResultConfiguration$OutputLocation . If none of them is set, Athena issues an error that no output location is provided. For more information, see Query Results .
The location in Amazon S3 where your query results are stored, such as s3://path/to/query/bucket/ . To run the query, you must specify the query results location using one of the ways: either for individual queries using either this setting (client-side), or in the workgroup, using WorkGroupConfiguration . If none of them is set, Athena issues an error that no output location is provided. For more information, see Query Results . If workgroup settings override client-side settings, then the query uses the settings specified for the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration .
If query results are encrypted in Amazon S3, indicates the encryption option used (for example, SSE_KMS or CSE_KMS ) and key information. This is a client-side setting. If workgroup settings override client-side settings, then the query uses the encryption configuration that is specified for the workgroup, and also uses the location for storing query results specified in the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration and Workgroup Settings Override Client-Side Settings .
Indicates whether Amazon S3 server-side encryption with Amazon S3-managed keys (SSE_S3 ), server-side encryption with KMS-managed keys (SSE_KMS ), or client-side encryption with KMS-managed keys (CSE_KMS ) is used.
If a query runs in a workgroup and the workgroup overrides client-side settings, then the workgroup's setting for encryption is used. It specifies whether query results must be encrypted, for all queries that run in this workgroup.
For SSE_KMS and CSE_KMS , this is the KMS key ARN or ID.
The Amazon Web Services account ID that you expect to be the owner of the Amazon S3 bucket specified by ResultConfiguration$OutputLocation . If set, Athena uses the value for ExpectedBucketOwner when it makes Amazon S3 calls to your specified output location. If the ExpectedBucketOwner Amazon Web Services account ID does not match the actual owner of the Amazon S3 bucket, the call fails with a permissions error.
This is a client-side setting. If workgroup settings override client-side settings, then the query uses the ExpectedBucketOwner setting that is specified for the workgroup, and also uses the location for storing query results specified in the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration and Workgroup Settings Override Client-Side Settings .
Indicates that an Amazon S3 canned ACL should be set to control ownership of stored query results. Currently the only supported canned ACL is BUCKET_OWNER_FULL_CONTROL . This is a client-side setting. If workgroup settings override client-side settings, then the query uses the ACL configuration that is specified for the workgroup, and also uses the location for storing query results specified in the workgroup. For more information, see WorkGroupConfiguration$EnforceWorkGroupConfiguration and Workgroup Settings Override Client-Side Settings .

For more information about Amazon S3 canned ACLs, see Canned ACL in the Amazon S3 User Guide .
If set to "true", the settings for the workgroup override client-side settings. If set to "false", client-side settings are used. For more information, see Workgroup Settings Override Client-Side Settings .
Indicates that the Amazon CloudWatch metrics are enabled for the workgroup.
The upper data usage limit (cutoff) for the amount of bytes a single query in a workgroup is allowed to scan.
If set to true , allows members assigned to a workgroup to reference Amazon S3 Requester Pays buckets in queries. If set to false , workgroup members cannot query data from Requester Pays buckets, and queries that retrieve data from Requester Pays buckets cause an error. The default is false . For more information about Requester Pays buckets, see Requester Pays Buckets in the Amazon Simple Storage Service Developer Guide .

Warning
This token is listed as not required because Amazon Web Services SDKs (for example the Amazon Web Services SDK for Java) auto-generate the token for users. If you are not using the Amazon Web Services SDK or the Amazon Web Services CLI, you must provide this token or the action will fail.
This field is autopopulated if not provided.
The database within which the query executes.
The name of the database used in the query execution. The database must exist in the catalog.
The name of the data catalog used in the query execution.
Specifies information about where and how to save the results of the query execution. If the query runs in a workgroup, then workgroup's settings may override query settings. This affects the query results location. The workgroup settings override is specified in EnforceWorkGroupConfiguration (true/false) in the WorkGroupConfiguration. See WorkGroupConfiguration$EnforceWorkGroupConfiguration .
The location in Amazon S3 where your query results are stored, such as s3://path/to/query/bucket/ . To run the query, you must specify the query results location using one of the ways: either for individual queries using either this setting (client-side), or in the workgroup, using WorkGroupConfiguration . If none of them is set, Athena issues an error that no output location is provided. For more information, see Query Results . If workgroup settings override client-side settings, then the query uses the settings specified for the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration .
If query results are encrypted in Amazon S3, indicates the encryption option used (for example, SSE_KMS or CSE_KMS ) and key information. This is a client-side setting. If workgroup settings override client-side settings, then the query uses the encryption configuration that is specified for the workgroup, and also uses the location for storing query results specified in the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration and Workgroup Settings Override Client-Side Settings .
Indicates whether Amazon S3 server-side encryption with Amazon S3-managed keys (SSE_S3 ), server-side encryption with KMS-managed keys (SSE_KMS ), or client-side encryption with KMS-managed keys (CSE_KMS ) is used.
If a query runs in a workgroup and the workgroup overrides client-side settings, then the workgroup's setting for encryption is used. It specifies whether query results must be encrypted, for all queries that run in this workgroup.
For SSE_KMS and CSE_KMS , this is the KMS key ARN or ID.
The Amazon Web Services account ID that you expect to be the owner of the Amazon S3 bucket specified by ResultConfiguration$OutputLocation . If set, Athena uses the value for ExpectedBucketOwner when it makes Amazon S3 calls to your specified output location. If the ExpectedBucketOwner Amazon Web Services account ID does not match the actual owner of the Amazon S3 bucket, the call fails with a permissions error.
This is a client-side setting. If workgroup settings override client-side settings, then the query uses the ExpectedBucketOwner setting that is specified for the workgroup, and also uses the location for storing query results specified in the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration and Workgroup Settings Override Client-Side Settings .
Indicates that an Amazon S3 canned ACL should be set to control ownership of stored query results. Currently the only supported canned ACL is BUCKET_OWNER_FULL_CONTROL . This is a client-side setting. If workgroup settings override client-side settings, then the query uses the ACL configuration that is specified for the workgroup, and also uses the location for storing query results specified in the workgroup. For more information, see WorkGroupConfiguration$EnforceWorkGroupConfiguration and Workgroup Settings Override Client-Side Settings .
The Amazon S3 canned ACL that Athena should specify when storing query results. Currently the only supported canned ACL is BUCKET_OWNER_FULL_CONTROL . If a query runs in a workgroup and the workgroup overrides client-side settings, then the Amazon S3 canned ACL specified in the workgroup's settings is used for all queries that run in the workgroup. For more information about Amazon S3 canned ACLs, see Canned ACL in the Amazon S3 User Guide .
A list of values for the parameters in a query. The values are applied sequentially to the parameters in the query in the order in which the parameters occur.
Specifies the query result reuse behavior for the query.
Specifies whether previous query results are reused, and if so, their maximum age.
True if previous query results can be reused when the query is run; otherwise, false. The default is false.
Specifies, in minutes, the maximum age of a previous query result that Athena should consider for reuse. The default is 60.

The Amazon Web Services account ID that you expect to be the owner of the Amazon S3 bucket specified by ResultConfiguration$OutputLocation . If set, Athena uses the value for ExpectedBucketOwner when it makes Amazon S3 calls to your specified output location. If the ExpectedBucketOwner Amazon Web Services account ID does not match the actual owner of the Amazon S3 bucket, the call fails with a permissions error.
If workgroup settings override client-side settings, then the query uses the ExpectedBucketOwner setting that is specified for the workgroup, and also uses the location for storing query results specified in the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration and Workgroup Settings Override Client-Side Settings .
If set to "true", removes the Amazon Web Services account ID previously specified for ResultConfiguration$ExpectedBucketOwner . If set to "false" or not set, and a value is present in the ExpectedBucketOwner in ResultConfigurationUpdates (the client-side setting), the ExpectedBucketOwner in the workgroup's ResultConfiguration is updated with the new value. For more information, see Workgroup Settings Override Client-Side Settings .
The ACL configuration for the query results.
The Amazon S3 canned ACL that Athena should specify when storing query results. Currently the only supported canned ACL is BUCKET_OWNER_FULL_CONTROL . If a query runs in a workgroup and the workgroup overrides client-side settings, then the Amazon S3 canned ACL specified in the workgroup's settings is used for all queries that run in the workgroup. For more information about Amazon S3 canned ACLs, see Canned ACL in the Amazon S3 User Guide .
If set to true , indicates that the previously-specified ACL configuration for queries in this workgroup should be ignored and set to null. If set to false or not set, and a value is present in the AclConfiguration of ResultConfigurationUpdates , the AclConfiguration in the workgroup's ResultConfiguration is updated with the new value. For more information, see Workgroup Settings Override Client-Side Settings .
Indicates whether this workgroup enables publishing metrics to Amazon CloudWatch.
The upper limit (cutoff) for the amount of bytes a single query in a workgroup is allowed to scan.
Indicates that the data usage control limit per query is removed. WorkGroupConfiguration$BytesScannedCutoffPerQuery
If set to true , allows members assigned to a workgroup to specify Amazon S3 Requester Pays buckets in queries. If set to false , workgroup members cannot query data from Requester Pays buckets, and queries that retrieve data from Requester Pays buckets cause an error. The default is false . For more information about Requester Pays buckets, see Requester Pays Buckets in the Amazon Simple Storage Service Developer Guide .
The engine version requested when a workgroup is updated. After the update, all queries on the workgroup run on the requested engine version. If no value was previously set, the default is Auto. Queries on the AmazonAthenaPreviewFunctionality workgroup run on the preview engine regardless of this setting.
The engine version requested by the user. Possible values are determined by the output of ListEngineVersions , including Auto. The default is Auto.
Read only. The engine version on which the query runs. If the user requests a valid engine version other than Auto, the effective engine version is the same as the engine version that the user requested. If the user requests Auto, the effective engine version is chosen by Athena. When a request to update the engine version is made by a CreateWorkGroup or UpdateWorkGroup operation, the EffectiveEngineVersion field is ignored.

Tags (list) --
The list of tags associated with the specified resource.
(dict) --
A label that you assign to a resource. In Athena, a resource can be a workgroup or data catalog. Each tag consists of a key and an optional value, both of which you define. For example, you can use tags to categorize Athena workgroups or data catalogs by purpose, owner, or environment. Use a consistent set of tag keys to make it easier to search and filter workgroups or data catalogs in your account. For best practices, see Tagging Best Practices . Tag keys can be from 1 to 128 UTF-8 Unicode characters, and tag values can be from 0 to 256 UTF-8 Unicode characters. Tags can use letters and numbers representable in UTF-8, and the following characters: + - = . _ : / @. Tag keys and values are case-sensitive. Tag keys must be unique per resource. If you specify more than one tag, separate them by commas.
Key (string) --
A tag key. The tag key length is from 1 to 128 Unicode characters in UTF-8. You can use letters and numbers representable in UTF-8, and the following characters: + - = . _ : / @. Tag keys are case-sensitive and must be unique per resource.
Value (string) --
A tag value. The tag value length is from 0 to 256 Unicode characters in UTF-8. You can use letters and numbers representable in UTF-8, and the following characters: + - = . _ : / @. Tag values are case-sensitive.
