Metacat is a unified metadata exploration API service from Netflix that federates metadata across data stores like Hive, RDS, Teradata, Redshift, S3, and Cassandra. It exposes a REST API for metadata discovery and allows storing arbitrary user metadata about datasets.

Use cases

  • federate metadata from hive, redshift, s3 and cassandra into one api
  • build a data catalog for discovering datasets across warehouses
  • query what data exists and where it resides
  • attach custom business metadata to tables and datasets
  • unify hive metastore metadata with other stores behind one rest service

When to choose

  • you need a federated metadata layer over multiple big data stores
  • you want a self-hosted data catalog with a REST API
  • you run a heterogeneous data platform and need unified dataset discovery

When to avoid

  • you need a full-featured modern data catalog with lineage and governance UIs
  • you only use a single data store with its own metastore
  • you want a managed SaaS catalog solution
