#parametersHash<String,String>

Specifies the Lambda function or functions to use for the data catalog. This is a mapping whose values depend on the catalog type.

  • For the HIVE data catalog type, use the following syntax. The metadata-function parameter is required. The sdk-version parameter is optional and defaults to the currently supported version.

    metadata-function=lambda_arn, sdk-version=version_number

  • For the LAMBDA data catalog type, use one of the following sets of required parameters, but not both.

    • If you have one Lambda function that processes metadata and another for reading the actual data, use the following syntax. Both parameters are required.

      metadata-function=lambda_arn, record-function=lambda_arn

    • If you have a composite Lambda function that processes both metadata and data, use the following syntax to specify your Lambda function.

      function=lambda_arn

  • The GLUE type takes a catalog ID parameter and is required. The catalog_id is the account ID of the Amazon Web Services account to which the Glue catalog belongs.

    catalog-id=catalog_id

    • The GLUE data catalog type also applies to the default AwsDataCatalog that already exists in your account, of which you can have only one and cannot modify.

    • Queries that specify a Glue Data Catalog other than the default AwsDataCatalog must be run on Athena engine version 2.

Returns:

  • (Hash<String,String>)
