Nov 1, 2025November 2025 monthly summary for couchbase/sync_gateway: Delivered a key concurrency optimization by refactoring ServerContext locking to use separate mutexes for databases and configurations, significantly reducing contention and improving throughput under concurrent workloads. This change strengthens scalability for multi-database operations and enhances overall reliability with lower lock-wait times. No user-facing features introduced; however, the improvement directly supports performance targets and stable operation in high-concurrency scenarios. Commit reference: CBG-5006: Split ServerContext mutexes (#7889) with hash 5bb2ae6cd97a6243547ff298ff40a18d4c3c6bf3.

Jan 1, 2025January 2025 monthly summary for couchbase/sync_gateway: Delivered substantive enhancements to replication, reliability, and observability. Key features include unidirectional replication support with client reuse optimization, enabling safer one-way syncs and reducing duplicate clients. Introduced background compaction metrics by counting scheduled runs as idle KV/Query operations, improving operational visibility. Expanded stats with a new 3.2.3 rebranching constant to support version tracking. Fixed critical bugs to improve stability and resource management: BlipTesterClient reliability improvements during replication and document updates; explicit release of unused sequences on CAS retries during principal updates to prevent leaks; preserving JSON document types in LeakyBucket during CAS retries; and removal of an unnecessary redundant test to streamline CI. These changes collectively boost data consistency, performance, and developer productivity.
