Sep 1, 2025Summary for 2025-09: Delivered two targeted improvements to the initial sync workflow in percona-server-mongodb. Feature: Enforced WiredTiger for file-copy-based initial syncs with an informative error when a non-WiredTiger engine is detected, improving compatibility and data integrity. Bug fix: Correct shutdown path during retries and temporary-directory cleanup by tracking the switch back to the original DB path before cleanup, preventing unintended engine shutdown. Impact: Increased reliability and predictability of initial syncs, reduced operational risk, and faster onboarding of new clusters. Technologies/skills demonstrated: storage-engine integration (WiredTiger), robust lifecycle management during retries/shutdowns, explicit error handling and traceable commits (1afb20e598cabca43485f4e4910acbaa5ada9e3d; 84027600abb4580fd8b561b5df26c2a67038bb07).

Aug 1, 2025August 2025 performance highlights focused on completing Bazel migration across core components, improving build reliability, and strengthening operational features and reporting. Delivered Bazel-based builds for key subsystems (libkmip/kmippp/libarchive, encryption, WiredTiger, telemetry, backup, and in-memory storage), enabling reproducible builds and faster iteration. Restored and stabilized audit feature integrity by re-establishing audit_impl dependency when audit is enabled. Improved Initial Syncer stability by fixing thread-safety in InitialSyncerFCB and ensuring replica set config is correctly converted to BSON to avoid build issues. Implemented build and script fixes to address Bazel integration quirks: making is_local_execution always true as a temporary workaround and removing obsolete DropPendingCollectionReaper references, plus related FCBIS build fixes. Strengthened backup reliability and reporting, including enhanced backup cursor error handling and test reliability, and reimplemented Percona-specific build metadata (psmdbVersion and proFeatures) to reflect enabled professional features. These changes collectively yield more reliable builds, clearer feature visibility, and faster deployment cycles.

Mar 1, 20252025-03 monthly summary for percona/percona-server-mongodb: Key reliability and data-consistency improvements across initial sync and backups. Implemented a controlled fail point (initialSyncHangAfterCloningFiles) and a denylist for failing FCBIS sync sources to stabilize initial sync and harden test infrastructure. Fixed backup cursor correctness by adding a replication state transition lock, retrieving last applied oplog time, and verifying visibility of earlier oplog writes to ensure oplogEnd is returned without holes. These changes reduce flaky test outcomes, improve bootstrap reliability, and strengthen data integrity in backup scenarios. Demonstrated skills: debugging replication internals, test instrumentation, logging, and CI/test tooling improvements.
