How does Scala support distributed metadata management in large data platforms?

Metadata systems track schemas, lineage, ownership, and governance across distributed datasets.

Scala-based data platforms integrate with metadata stores (Hive Metastore, Apache Atlas, Amundsen). Metadata includes schema definitions, data lineage graphs, and ownership information. This enables governance, discoverability, and compliance. Metadata services are often event-driven, updating catalogs as pipelines evolve.
