October 2025 monthly summary for percona/percona-server-mysql-operator: Delivered two key features to improve data quality and deployment robustness, with emphasis on business value and operator reliability. Implemented Telemetry Data Quality Improvements to drop empty metrics, and added Proxy Configuration Validation to prevent conflicts between MySQL Router and HAProxy. These changes reduce bad telemetry data, prevent misconfigurations, and improve deployment stability. Skills demonstrated include Kubernetes operator development, conditional metric generation, and config validation, resulting in cleaner telemetry, easier troubleshooting, and higher customer trust.

In September 2025, the Percona Server MySQL Operator contributed substantial telemetry capabilities, API modernization, and reliability improvements that enhance observability, deployment safety, and testing rigor across the operator. Key work spanned end-to-end telemetry delivery, lifecycle management, and test infrastructure, with targeted changes that deliver immediate business value for cluster monitoring, maintenance automation, and upgrade readiness.

Concise monthly summary for 2025-08 focused on delivering operator reliability, predictable service management, and enhanced health monitoring for the Percona Server MySQL Operator.

Month: 2025-07. Delivered key feature: Expose primary MySQL service for Group Replication (GR) clusters by introducing an exposePrimary field in the MySQLSpec to configure and create a Kubernetes Service for the primary MySQL node. The service supports configurable type, annotations, and labels, enhancing accessibility and manageability of the primary node. This work reduces manual steps and improves GR cluster deployment reliability.

June 2025: Focused feature delivery across the Percona Server MySQL operator to improve deployment flexibility, reliability, and lifecycle management. No critical bugs fixed this month; stability improvements accompanied feature work. Key outcomes include storage options for hostPath/emptyDir with enhanced validation and tests, CR-level replica size validations for group_replication, and configurable termination grace periods across components with a PodSpec refactor to GetTerminationGracePeriodSeconds, enabling safer shutdowns and scalable deployments. These changes reduce misconfigurations, enable use of node-local storage, and improve production readiness. Technologies demonstrated include Kubernetes CRDs and API type validation, Go-based operator logic, end-to-end testing, and lifecycle management.

May 2025 focused on stabilizing end-to-end (e2e) test automation for the percona-server-mysql-operator repository. The month delivered a critical test configuration fix to ensure PMM server image configuration is exercised correctly in CI, and a practical test infrastructure enhancement to improve cleanup reliability. These changes reduced test flakiness, improved deployment validation, and strengthened CI feedback loops for faster iteration.

March 2025: Delivered core operator enhancements for Percona Server MySQL to improve security, reliability, and maintainability. Key work included upgrading PMM integration and modernizing authentication, introducing async cluster validations with defaults, and cleansing the codebase for clarity and sustainability. These changes reduce operational risk, improve PMM deployments, and set the foundation for future feature work.

February 2025: Delivered two key CI pipeline updates aligning Kubernetes versions across repositories. MongoDB operator Jenkins pipeline now provisions auto-created clusters with Kubernetes 1.29 (commit 3cd25bf50d7c8aead50b730ead2b8f94c7c500cd). MySQL operator CI deployments updated to Kubernetes 1.29 (commit 9de75cd98451909c245d6a37a6f4b53575ed16a6). Major bugs fixed: none reported this month. Impact: reduces drift between CI/testing environments and supported Kubernetes version, improves provisioning reliability and test fidelity, and streamlines upgrade paths. Technologies/skills demonstrated: Jenkins pipelines, Kubernetes 1.29, CI/CD best practices, YAML/config pinning, and cross-repo collaboration with clear Git commit traceability.

January 2025: Maintained and strengthened operator quality through targeted code cleanup, robust error handling, test standardization, and deployment hardening across MongoDB and MySQL operators. Delivered concrete features with measurable impact on stability and maintainability, and advanced automation readiness through E2E improvements and config enforcement.
