Response Structure
A list of crawler definitions.
Specifies a crawler program that examines a data source and uses classifiers to try to determine its schema. If successful, the crawler records metadata concerning the data source in the Glue Data Catalog.
The name of the crawler.
The Amazon Resource Name (ARN) of an IAM role that's used to access customer resources, such as Amazon Simple Storage Service (Amazon S3) data.
A collection of targets to crawl.
Specifies Amazon Simple Storage Service (Amazon S3) targets.
Specifies a data store in Amazon Simple Storage Service (Amazon S3).
The path to the Amazon S3 target.
A list of glob patterns used to exclude from the crawl. For more information, see Catalog Tables with a Crawler.
The name of a connection which allows a job or crawler to access data in Amazon S3 within an Amazon Virtual Private Cloud environment (Amazon VPC).
Sets the number of files in each leaf folder to be crawled when crawling sample files in a dataset. If not set, all the files are crawled. A valid value is an integer between 1 and 249.
A valid Amazon SQS ARN. For example, arn:aws:sqs:region:account:sqs .
A valid Amazon dead-letter SQS ARN. For example, arn:aws:sqs:region:account:deadLetterQueue .
Specifies JDBC targets.
Specifies a JDBC data store to crawl.
The name of the connection to use to connect to the JDBC target.
The path of the JDBC target.
A list of glob patterns used to exclude from the crawl. For more information, see Catalog Tables with a Crawler.
Specify a value of RAWTYPES or COMMENTS to enable additional metadata in table responses. RAWTYPES provides the native-level datatype. COMMENTS provides comments associated with a column or table in the database.
If you do not need additional metadata, keep the field empty.
Specifies Amazon DocumentDB or MongoDB targets.
Specifies an Amazon DocumentDB or MongoDB data store to crawl.
The name of the connection to use to connect to the Amazon DocumentDB or MongoDB target.
The path of the Amazon DocumentDB or MongoDB target (database/collection).
Indicates whether to scan all the records, or to sample rows from the table. Scanning all the records can take a long time when the table is not a high throughput table.
A value of true means to scan all records, while a value of false means to sample the records. If no value is specified, the value defaults to true .
Specifies Amazon DynamoDB targets.
Specifies an Amazon DynamoDB table to crawl.
The name of the DynamoDB table to crawl.
Indicates whether to scan all the records, or to sample rows from the table. Scanning all the records can take a long time when the table is not a high throughput table.
A value of true means to scan all records, while a value of false means to sample the records. If no value is specified, the value defaults to true .
The percentage of the configured read capacity units to use by the Glue crawler. Read capacity units is a term defined by DynamoDB, and is a numeric value that acts as rate limiter for the number of reads that can be performed on that table per second.
The valid values are null or a value between 0.1 to 1.5. A null value is used when user does not provide a value, and defaults to 0.5 of the configured Read Capacity Unit (for provisioned tables), or 0.25 of the max configured Read Capacity Unit (for tables using on-demand mode).
Specifies Glue Data Catalog targets.
Specifies an Glue Data Catalog target.
The name of the database to be synchronized.
A list of the tables to be synchronized.
The name of the connection for an Amazon S3-backed Data Catalog table to be a target of the crawl when using a Catalog connection type paired with a NETWORK Connection type.
A valid Amazon SQS ARN. For example, arn:aws:sqs:region:account:sqs .
A valid Amazon dead-letter SQS ARN. For example, arn:aws:sqs:region:account:deadLetterQueue .
Specifies Delta data store targets.
Specifies a Delta data store to crawl one or more Delta tables.
A list of the Amazon S3 paths to the Delta tables.
The name of the connection to use to connect to the Delta table target.
Specifies whether to write the manifest files to the Delta table path.
Specifies whether the crawler will create native tables, to allow integration with query engines that support querying of the Delta transaction log directly.
The name of the database in which the crawler's output is stored.
A description of the crawler.
A list of UTF-8 strings that specify the custom classifiers that are associated with the crawler.
A policy that specifies whether to crawl the entire dataset again, or to crawl only folders that were added since the last crawler run.
Specifies whether to crawl the entire dataset again or to crawl only folders that were added since the last crawler run.
A value of CRAWL_EVERYTHING specifies crawling the entire dataset again.
A value of CRAWL_NEW_FOLDERS_ONLY specifies crawling only folders that were added since the last crawler run.
A value of CRAWL_EVENT_MODE specifies crawling only the changes identified by Amazon S3 events.
The policy that specifies update and delete behaviors for the crawler.
The update behavior when the crawler finds a changed schema.
The deletion behavior when the crawler finds a deleted object.
A configuration that specifies whether data lineage is enabled for the crawler.
Specifies whether data lineage is enabled for the crawler. Valid values are:
Indicates whether the crawler is running, or whether a run is pending.
The prefix added to the names of tables that are created.
For scheduled crawlers, the schedule when the crawler runs.
A cron expression used to specify the schedule (see Time-Based Schedules for Jobs and Crawlers. For example, to run something every day at 12:15 UTC, you would specify: cron(15 12 * * ? *) .
The state of the schedule.
If the crawler is running, contains the total time elapsed since the last crawl began.
The time that the crawler was created.
The time that the crawler was last updated.
The status of the last crawl, and potentially error information if an error occurred.
Status of the last crawl.
If an error occurred, the error information about the last crawl.
The log group for the last crawl.
The log stream for the last crawl.
The prefix for a message about this crawl.
The time at which the crawl started.
The version of the crawler.
Crawler configuration information. This versioned JSON string allows users to specify aspects of a crawler's behavior. For more information, see Setting crawler configuration options.
The name of the SecurityConfiguration structure to be used by this crawler.
Specifies whether the crawler should use Lake Formation credentials for the crawler instead of the IAM role credentials.
Specifies whether to use Lake Formation credentials for the crawler instead of the IAM role credentials.
Required for cross account crawls. For same account crawls as the target data, this can be left as null.
A list of names of crawlers that were not found.
