Parameters

Specifies the Lambda function or functions to use for creating 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 AWS account to which the AWS Glue Data 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.
