Advancing Apache Iceberg on Databricks: Iceberg v3 GA, Open Sharing, and Unified Governance
Unity Catalog now offers GA support for Managed Iceberg, Iceberg v3, and Foreign Iceberg, making it the most comprehensive and production-ready Apache Iceberg catalog with open APIs, catalog federation, and secure sharing. Future versions of Iceberg and Delta will converge on a unified metadata structure, eliminating the tradeoff between interoperability and performance.
*Unity Catalog is now the most comprehensive, interoperable, and production-ready Apache Iceberg catalog, with Managed Iceberg, Iceberg v3, and Foreign Iceberg moving into GA. *Five capabilities set it apart: open APIs, catalog federation, cross-engine access control, zero-copy secure sharing, and AI-driven optimization. *Looking ahead, Iceberg v4 and Delta 5.0 will converge on a unified metadata structure, ending the tradeoff between interoperability and production-ready performance.
