Data Swamp

A data lake that has become unusable because of missing metadata, governance and quality controls.

Definition

Without cataloging, ownership, lineage and quality checks, users cannot find or trust data in the lake. Catalogs such as Unity Catalog, Purview, Glue Data Catalog and Dataplex help prevent swamps.

Exam tip

The fix for a data swamp is governance plus a data catalog, not more storage.
