May 2026 monthly summary for StarRocks/starrocks focusing on robustness, concurrency, and security improvements. Key changes include: (1) Locker locking safety improvements: added a rollback mechanism for partial intensive-lock acquisitions and ensured proper unlock order to prevent deadlocks and resource leaks, improving exception safety during lock rollbacks. (2) Fine-grained locking to improve concurrency: relaxed DB read locks for single-table procedure directories and table-level locking to boost concurrency and performance; added tests for non-existent partition lookups. (3) Dependency upgrades: StarOS runtime upgraded to v4.1-rc4 and security libraries updated (PostgreSQL JDBC driver to 42.7.11 and BouncyCastle to 1.84) to address vulnerabilities and enhance cryptographic capabilities. (4) LakePublishBatchTest stability fix: resolved a race condition by ensuring the correct transaction batch is selected based on the table ID, preventing stale-batch assertions. Overall impact: improved stability, security posture, and throughput, enabling more reliable releases and safer concurrency under heavy workloads.

April 2026 delivered stability, security hardening, and targeted feature improvements for StarRocks/starrocks, with a focus on reliability, performance, and observability that translate to business value. Key features delivered include a BE-side metric for cache-miss shard info fallback in StarOSWorker and a Batch tablet-location lookup in OlapTableSink.createLocation, both enhancing operational visibility and planning efficiency. A regression test for GCS cache key underscores was added to strengthen cloud-storage reliability. In addition, we completed essential build-system and broker-FE integration work to streamline CI/CD and dependency hygiene. Major bugs fixed spanned CVE remediation and build stabilization, replication availability improvements in StarMgr/StarOS, and significant DB-lock and REST-endpoint optimizations that reduce contention and improve latency. Ongoing refactoring also relaxed DB READ/WRITE locking and introduced runtime configurability for critical sync intervals. Technologies/skills demonstrated include Go toolchain and CVE remediation across builds (including go1.25.9 compatibility), performance-oriented lock optimization, metrics instrumentation, and cloud-storage regression testing, all contributing to a more secure, stable, and scalable platform.

Concise monthly summary for StarRocks/starrocks, March 2026.
