Feb 1, 2026February 2026 (2026-02) highlights for apache/gravitino: Delivered comprehensive ClickHouse catalog and table management enhancements with cluster mode, distributed and partitioning support, create/drop/load/list operations, ALTER capabilities, and indexing refinements, backed by targeted UTs/ITs. Expanded Lance table functionality to drop and rename columns with updated REST endpoints and tests. Fixed critical correctness issues in JDBC catalogs (default value handling for string-type columns) and in table columns loading (more robust SQL and logging). Implemented RC version parsing enhancements to improve release validation. Improved caching for non-existence relational data and invalidation on new relations to boost load performance. Stabilized CI/build infrastructure with dependency updates, testcontainers improvements, and workflow optimizations to shorten feedback loops. Overall, these efforts delivered production-ready catalog features, higher reliability, and better performance, enabling faster feature delivery and stronger data governance." ,

Dec 1, 2024December 2024 highlights for apache/gravitino focus on expanding cloud storage support and improving Hadoop compatibility. Delivered Google Cloud Storage (GCS) integration for the Hive catalog, including Docker image updates with GCS connectors, an integration test, and updated documentation to reflect GCS usage. Completed a dependency and build refactor for cloud storage integrations (AWS, GCP, Aliyun, Azure) to improve Hadoop compatibility by introducing a dedicated hadoop-common module and redesigning bundle JARs to exclude Hadoop-specific dependencies, reducing version conflicts across Hadoop 2.x/3.x environments. As part of compatibility hardening, removed the GVFS client configuration fs.gvfs.filesystem.providers to streamline Hadoop3-filesystem behavior. These changes enable smoother multi-cloud data lake adoption, easier upgrades, and lower operational risk.
