Jun 1, 2026June 2026 (2026-06) — Delivered a centralized test utility for session cache refresh logic in percona/percona-server-mongodb. Extracted shared logical session cache refresh serialization tests into a helper library, added a dedicated test file, and refactored the main test to delegate refresh logic to the helper. These changes reduce duplication, improve test organization, and streamline future test updates, enhancing test reliability for session cache behavior.

Feb 1, 2026February 2026 highlights for percona/percona-server-mongodb: Key feature delivered was the Flexible MetricName constructor, enabling creation outside the MetricNames class and broadening metric handling across the server. This change is supported by the commit 0b9f7ec90e26e972c9cf284b8bae7e50daef152b (SERVER-119072) and includes co-authored contributions with explicit GitOrigin-RevId metadata. The update lays groundwork for future module-based access restrictions and improves observability by enabling more flexible instrumentation across contexts. There were no major bug fixes in February for this repository; the focus was on feature delivery and architectural groundwork. Impact: enhances metrics observability, reduces instrumentation friction, and prepares the codebase for modular usage boundaries. Technologies/skills demonstrated: metrics subsystem design, cross-team collaboration and attribution, and rigorous change traceability.

Jan 1, 2026January 2026 monthly summary for percona/percona-server-mongodb: Focused on improving startup reliability, data integrity, and maintainability. Delivered two major features: Offline Validation Startup Support and Startup Reliability and Recovery Improvements. Also fixed an MDB Catalog invariant preventing collection creation when the catalog was uninitialized, and synchronized dependencies with a MODULE.bazel.lock update. These changes reduce startup downtime, ensure safe startup validation with no user connections, prevent errors during collection creation, and keep the build in sync with dependencies, delivering measurable business value through increased reliability and reduced maintenance costs.
