PROFILE
Tim Stoop
Tim Stoop developed configurable HAProxy health checks for the percona/percona-xtradb-cluster-operator, enabling operators to fine-tune health-check behavior directly from the custom resource specification. He implemented these changes using Go and Kubernetes, updating deployment scripts and StatefulSet generation to propagate health-check options as environment variables while maintaining backward compatibility through careful ordering and version gating. Tim expanded both unit and end-to-end test coverage and updated comparison baselines to ensure stable upgrades and predictable health-check behavior. By consolidating redundant logic and simplifying the API, his work improved cluster reliability and gave operators more granular control over cloud infrastructure operations.

Nov 1, 2025Monthly summary for 2025-11: Delivered configurable HAProxy health checks for the Percona XtraDB Cluster Operator, enabling operators to tune health-check behavior directly from the CR spec and align with upstream changes. Implemented changes in deployment scripts and StatefulSet generation to propagate health-check options as environment variables, with careful attention to ordering and defaults to ensure backward compatibility. Expanded test coverage (unit and e2e) and updated comparison baselines to stabilize upgrades and health-check behavior. Strengthened upgrade safety through version gating (1.19.0+) for health-check env vars and simplified the API by removing the redundant ShutdownOnMarkDown logic and consolidating behavior into SERVER_OPTIONS. Overall, these efforts improve reliability, operability, and business value by reducing downtime risk and giving operators granular control over cluster health.
