Worked on the percona/percona-server-mongodb repository to enhance resharding observability, reliability, and test stability using C++ and MongoDB. Developed new serverStatus and log metrics to improve diagnostics for resharding validation, and expanded change stream monitoring by adding assertions and system event tracking. Addressed race conditions in the resharding cancellation flow with failpoints, ensuring robust step-up recovery. Improved test reliability by restructuring config server tests to reduce flaky timeouts. Additionally, extended retryable error handling in the config stepdown process using JavaScript, enabling automated retries for HostUnreachable errors and increasing system resilience during transient network interruptions.
