Response Structure

  • (dict) –

    • DataCatalog (dict) –

      The data catalog returned.

      • Name (string) –

        The name of the data catalog. The catalog name must be unique for the Amazon Web Services account and can use a maximum of 127 alphanumeric, underscore, at sign, or hyphen characters. The remainder of the length constraint of 256 is reserved for use by Athena.

      • Description (string) –

        An optional description of the data catalog.

      • Type (string) –

        The type of data catalog to create: LAMBDA for a federated catalog, HIVE for an external hive metastore, or GLUE for an Glue Data Catalog.

      • Parameters (dict) –

        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.
