11 Commits • 2 Features
Mar 1, 2026March 2026 focused on delivering the Replicated Fast Count (RFC) feature for MongoDB in percona-server-mongodb, enhanced observability, and strengthened test infrastructure. RFC was delivered with feature flag support, metrics collection (including FTDC metrics), and thread-safety improvements to ensure reliable fast-count operations across replication scenarios. Added ObservableMutex-based synchronization in the ReplicatedFastCountManager and improved shutdown behavior. Test stability was improved via RFC build variant stabilization, including disabling failing tests and enabling disk_wiredtiger testing and noPassthrough variants. Observability tooling and docs were updated, including evergreen binary discovery improvements and OpenTelemetry metrics documentation. Overall, these efforts increased replication accuracy, reduced risk in deployments, and accelerated feedback through better monitoring and test coverage.
