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.

Metadata Extraction Queries

To use query-based metadata extraction, you will need to write custom queries to extract the metadata. Alation expects that these queries conform to a specific structure and use some reserved identifiers. After providing custom queries, save them by clicking Save in this section.

Refer to Extraction Queries for Teradata for information about query customization.
