The OCF Connector for Impala on CDP supports default extraction—This type of MDE is based on default Metastore API calls that are built in the connector code.

Custom query-based MDE is not supported.

Note

Impala on CDP supports extraction of complex data types. For information on how to enable their representation in the Alation user interface, see the Extract Complex Data Types section in Prerequisites.

You can configure metadata extraction (MDE) for an OCF data source on the Metadata Extraction tab of the Settings page. Refer to Configure Metadata Extraction for OCF Data Sources for information about the available configuration options.
