Worked on the apache/gravitino repository, focusing on backend development, dependency management, and build automation using Java, Kotlin, and Gradle. Over four months, delivered features and fixes that improved cloud storage compatibility, CI reliability, and database stability. Addressed integration with GCS by implementing secure credential handling, stabilized UI and integration tests, and optimized build performance through selective dependency exclusions and upgrades. Enhanced Flink connector reliability and maintained SQL compatibility by updating libraries and refining query syntax. All changes were validated with comprehensive unit and integration testing, resulting in a leaner, more maintainable codebase without introducing user-facing modifications.

Jun 1, 2026June 2026 — apache/gravitino (repo focus: dependencies and database stability) Key outcomes: - Dependency footprint reduction and build simplification: Removed unused transitive dependencies across catalogs/modules to streamline the build, reduce artifact footprint, and improve maintainability. Notable cleanups include removing htrace-core4, unused Arrow transitive in hive-metastore3-libs, exclusion of tomcat-embed-core in the hive-exec path, and removing legacy Netty 3.x. These changes are associated with PRs #11314, #11326, #11337, and #11345. Verification included compilation across affected modules and unit tests; distribution outputs no longer contain the removed jars. - Database compatibility and stability upgrade: Upgraded H2 database from 1.4.200 to 2.2.224 and fixed JOIN syntax in TagMetadataObjectRelBaseSQLProvider to comply with H2 2.x parsing rules. This aligns development/testing stability with the updated SQL semantics (PR #11350). All core tests continue to pass across affected areas. Overall impact and accomplishments: - Reduced dependency surface area, leading to faster builds and cleaner deployments. - Improved development/test stability and compatibility with modern SQL parsers. - No user-facing changes; changes are internal to dependencies and SQL handling, reducing risk in production. Technologies/skills demonstrated: - Gradle/Kotlin DSL build tooling and dependency management - Libraries/version management (libs.versions.toml) and multi-module coordination - SQL compatibility adjustments and regression testing across modules - Cross-module validation (compile + unit tests) indicating robust change control

Apr 1, 2026Month: 2026-04 — Consolidated effort to prune unused transitive dependencies across the apache/gravitino workspace, reducing runtime footprint and improving build efficiency. The work focused on a multi-module dependency clean-up across catalogs and Hive metastore libraries, with thorough validation via compile and unit tests. No user-facing features were introduced; the impact is reduced artifact size, leaner runtime classpath, and lower risk of dependency conflicts, which supports faster CI cycles and more stable production deployments.
