Apr 1, 2025April 2025 (2025-04) — Repository: percona/percona-server-mongodb Key features delivered: - Shard AddShard Reliability and FCV Synchronization: enhanced the addShard workflow to synchronize the Feature Compatibility Version (FCV) with new shards, prevent adds during FCV upgrades/downgrades, and improve lock ordering and coordinator management for stable topology updates. - AddShard operation locking for concurrency safety: introduced a dedicated lock to serialize concurrent addShard calls, eliminating race conditions and ensuring safe access to the sharding catalog. - Connectivity check to config server: added an internal command to verify connectivity from the replica set to the config server, enabling early failure if the config server is unreachable. - Resilient topology changes enabled by default: activated the resilient topology change mechanism by default in 8.2, with associated IDL and test updates. - Testability and maintenance improvements: removed the internal test command in favor of using the coordinator directly for addShard operations, and introduced multiversion test markers to cover removed commands; added background shard-testing scaffolding to validate robustness under dynamic conditions. Major bugs fixed: - Graceful duplicate-key handling in AddShard coordination: addShard now swallows duplicate key errors on subsequent attempts, preventing failures due to duplicates and increasing robustness of shard coordination. Overall impact and accomplishments: - Significantly improved reliability and safety of shard topology changes, reducing operational risk during shard additions and topology updates. - Enhanced failure detection and resilience through early config-server connectivity checks and default-enabled resilient topology changes. - Strengthened testing and maintenance practices, with broader multiversion coverage and streamlined operational commands. Technologies/skills demonstrated: - Distributed coordination patterns (coordinator-based addShard flow), locking and race-condition prevention, and FCV-aware operations. - Internal command design, fail-fast checks, and feature flag management. - Testing strategies, including multiversion coverage, background operation testing, and refactoring of internal testing commands.
