Buf Announces Support for Unity Catalog Managed Iceberg Tables
We’re announcing a major step toward our vision of a single schema definition in Protobuf that governs your entire data flow — from API contracts to streaming topics to analytical tables. Bufstream now supports Databricks Managed Iceberg Tables in private preview, bringing together Buf's schema-first approach with Databricks' industry-leading data governance and optimization capabilities. This integration represents more than just technical compatibility—it's a fundamental shift toward treating schemas as the foundation of your entire data architecture.
