Apache Iceberg™ Interoperability: First-Class Open Support in Databricks Delta Sharing

Open data sharing across platform boundaries is now a reality. As organizations move toward multi-engine environments, collaborating across different catalogs and ecosystems is a strategic necessity. With the launch of first-class Iceberg support in Databricks Delta Sharing, you can maintain a single governance layer while supporting a diverse, multi-platform data estate.

Key Highlights:

• First-Class Iceberg Support: Share Delta tables as native Iceberg tables via the Iceberg REST Catalog API for zero-copy sharing to Snowflake, Trino, and Spark.
• Bi-Directional Interoperability: Bring ""foreign"" Iceberg tables from AWS Glue or Snowflake into Unity Catalog and share them to any recipient.
• Unified Governance: Share fine-grained Views via secretless authentication, even to non-Databricks platforms.
• Open Standards, No Lock-In: Shift from closed sharing models to a transparent protocol that supports multiple clouds, formats, and platforms simultaneously.
