Unity Catalog — Unified Data Governance for Databricks Lakehouse
Unity Catalog is Databricks' unified governance layer for data, analytics, and AI assets. It provides a single place to manage permissions, audit access, discover data, and enforce governance policies across all Databricks workspaces — replacing the fragmented per-workspace security model with centralized, enterprise-grade governance.
What Is Unity Catalog and How Enterprises Use It
Unity Catalog provides fine-grained governance for the Databricks lakehouse: tables, views, volumes (files), models, functions, and notebooks — all governed through a single metastore. It replaces the legacy Hive metastore approach where each workspace had its own catalog with no cross-workspace visibility or governance.
Key capabilities: centralized access control (GRANT/REVOKE at catalog, schema, and table level), data lineage (automatic column-level lineage tracking across notebooks and jobs), data discovery (searchable catalog with tags, descriptions, and ownership), audit logging (who accessed what data, when, from which workspace), row-level and column-level security (attribute-based access control for sensitive data), and Delta Sharing (secure data sharing across organizations without data copying).
Why it matters: without Unity Catalog, Databricks governance is per-workspace — 10 workspaces means 10 separate permission sets, no cross-workspace lineage, and no centralized audit trail. Unity Catalog unifies governance across all workspaces, enabling: enterprise data governance, regulatory compliance (HIPAA, GDPR, SOX audit trails), and self-service data discovery for analytics teams.
