13 Commits • 3 Features
Mar 1, 2026March 2026: Delivered end-to-end Trino connector ecosystem improvements and automation for the Gravitino project. Key features: multi-version Trino connector distribution (435–478) with a version-segment module and updated base image to 478; automated Docker image building/publishing via GitHub Actions with non-interactive release mode. Key reliability work: removed unrecognized JVM option for Trino 478+, aligned JVM config; integrated multi-version CI tests across 435–478 to prevent regressions. Compliance and packaging: license/NOTICE fixes, release notes updates, and packaging hygiene (missing __init__.py, distribution size reductions). Result: faster, more reliable releases, better compatibility across Trino versions, and improved governance.

Sep 1, 2025September 2025 monthly summary for apache/gravitino: Delivered two critical improvements: refined version compatibility checks for Gravitino client-server and resolution of build/classpath conflicts in cloud bundles across AWS, Aliyun, Azure, and GCP. These changes enhance deployment reliability and runtime stability while showcasing strong Gradle-based dependency management and cross-cloud packaging capabilities. Key outcomes include improved client version matching by considering major and minor versions, reduced risk from patch-level discrepancies, increased build stability by updating dependencies to compileOnly/testImplementation and removing ShadowJar relocations, and improved runtime classpath integrity across cloud bundles. Overall, higher deployment confidence, fewer integration issues, and clearer, maintainable build configurations.
