<p>Specifies the Lambda function or functions to use for creating the data catalog. This is a mapping whose values depend on the catalog type. </p> <ul> <li> <p>For the <code>HIVE</code> data catalog type, use the following syntax. The <code>metadata-function</code> parameter is required. <code>The sdk-version</code> parameter is optional and defaults to the currently supported version.</p> <p> <code>metadata-function=<i>lambda_arn</i>, sdk-version=<i>version_number</i> </code> </p> </li> <li> <p>For the <code>LAMBDA</code> data catalog type, use one of the following sets of required parameters, but not both.</p> <ul> <li> <p>If you have one Lambda function that processes metadata and another for reading the actual data, use the following syntax. Both parameters are required.</p> <p> <code>metadata-function=<i>lambda_arn</i>, record-function=<i>lambda_arn</i> </code> </p> </li> <li> <p> If you have a composite Lambda function that processes both metadata and data, use the following syntax to specify your Lambda function.</p> <p> <code>function=<i>lambda_arn</i> </code> </p> </li> </ul> </li> <li> <p>The <code>GLUE</code> type takes a catalog ID parameter and is required. The <code> <i>catalog_id</i> </code> is the account ID of the Amazon Web Services account to which the Glue Data Catalog belongs.</p> <p> <code>catalog-id=<i>catalog_id</i> </code> </p> <ul> <li> <p>The <code>GLUE</code> data catalog type also applies to the default <code>AwsDataCatalog</code> that already exists in your account, of which you can have only one and cannot modify.</p> </li> <li> <p>Queries that specify a Glue Data Catalog other than the default <code>AwsDataCatalog</code> must be run on Athena engine version 2.</p> </li> <li> <p>In Regions where Athena engine version 2 is not available, creating new Glue data catalogs results in an <code>INVALID_INPUT</code> error.</p> </li> </ul> </li> </ul>
