July 2026 monthly summary for percona/percona-server-mysql-operator focusing on delivering reliable end-to-end backup and restore capabilities, addressing test stability, and strengthening code quality. Highlighted features and bug work include extensive test improvements for scheduled backups, timeout adjustments, and lint fixes for backup verification. Focused on business value through stable backup/restore pipelines and improved developer productivity.

June 2026 Monthly Summary Overview: Delivered reliability, performance improvements, and expanded testing capabilities across two core repos: percona-xtradb-cluster-operator and Jenkins pipelines. Focused on strengthening data integrity, accelerating cluster operations, and improving CI/CD usability for certifiable images. Key Deliveries (by repo): - percona/percona-xtradb-cluster-operator • Reliable Backup and Cross‑Node Recovery (feature): Adds cross-node recovery verification and health-based backup gating to prevent data corruption when the cluster is unhealthy. Commits include f77dc4bc29b082f63d614f048449f13b29abaf85 (Fix comment) and a205b8fc836140f0e8b983b17d212f8163106075 (Remove unnecessary steps for backup failure state). • Cluster Waiting Optimization and Data Insertion Helper (feature): Optimizes cluster waiting behavior by skipping waits for proxy components when not enabled and introduces a write_data helper to streamline data insertion. Commit: 2014648a1ff320a321e7d4e246f2e1fdba225c79 (Skip waiting for proxy when not enabled). • Testing Framework Improvements and Debugging Utilities (feature): Enhances test tooling with debugging capabilities, improved readability of test SQL, and support for a custom port in proxy-protocol tests. Commits: c394121ffbb2ae6c2e23cf267d64a381c0846dbe (Set debug), 05628074f34ce7c48bed16a02845218a59fd33d9 (Use new line to split data items as pitr tests), e31dfdf268ef4fd78756b3c302f29165318a1e8c (Allow custom port for proxy-protocol test). - Percona-Lab/jenkins-pipelines • Granular certifiable image controls in Jenkins pipeline (feature): Introduces a structured list of certifiable images for the certification process, enabling granular control over which images to certify and improving workflow clarity. Commit: 26bb176862291119db102e2827885eb3467e3606 (Certification images list (#4161)). Major Bugs Fixed / Reliability Improvements: - Data integrity safeguard: Backups are gated by cluster health, reducing the risk of corrupt backups and ensuring recovery verification across nodes. - Testing stability enhancements: Debugging utilities and configurable proxy-port support reduce flaky test runs and improve test coverage reliability. Overall Impact and Accomplishments: - Strengthened data safety and operational reliability for multi-node deployments with targeted backup/recovery controls and health-based gating. - Reduced latency in cluster operations via smarter waiting logic, and simplified data insertion through a dedicated helper. - Expanded testing coverage and reliability, enabling more flexible and thorough validation in CI environments. - Improved CI/CD usability and governance with granular image certification controls in Jenkins pipelines. Technologies/Skills Demonstrated: - Go-based operator development patterns, Kubernetes cluster management, and backup/recovery architectures. - Test automation, debugging tooling, and flexible testing pipelines (proxy-protocol tests, custom ports). - CI/CD design and governance for image certification in Jenkins.

May 2026 monthly summary for developer work across Percona-related repositories. Focused on delivering feature-rich pipelines, reliability improvements, and release-ready upgrades across Kubernetes and PostgreSQL ecosystems. Highlights include new image certification and selective build workflows, configurable Kubernetes upgrade paths, and a coordinated 3.0.0 release across operator infra and ecosystems, all backed by security patches and improved diagnostics.

April 2026: Focused on reliability, upgrade readiness, and maintainability across Percona's Kubernetes operators. Key delivery included a binlog deployment compatibility update for the MySQL operator (image alignment with the latest release and cleanup of deprecated backup fields) and an end-to-end Kubernetes upgrade/testing approach for the PostgreSQL operator across GKE and DOKS. Also delivered code quality improvements for Kubernetes cluster management, centralizing version verification to streamline upgrades. These efforts reduce deployment friction, accelerate upgrade paths, and improve overall operational resilience.
