Worked on the pingcap/tidb-operator repository to enhance the stability and reliability of volume replacement workflows in Kubernetes-based distributed systems. Addressed issues where active TiKV leaders and unready PD members during volume replacement caused excessive CPU and IO usage, latency spikes, and potential cluster state inconsistencies. Introduced a pre-eviction step for TiKV leaders before replacement and enforced PD readiness checks prior to status updates, reducing the risk of degraded performance and zombie PD members. All changes were implemented in Go, leveraging expertise in cloud native operations, distributed systems, and system administration to deliver safer, more predictable maintenance for stateful clusters.

Jun 1, 2025June 2025 monthly summary for pingcap/tidb-operator focusing on volume replacement stability and cluster reliability. Delivered stability fixes to the volume replacement workflow by reverting the eviction policy on pods being deleted and enforcing PD readiness before updating status, reducing CPU/IO spikes and preventing zombie PD members from invalidating cluster state during replacement. These changes enhance maintenance safety, reduce latency spikes, and lower the risk of degraded performance during volume replacement.

Feb 1, 2025February 2025 monthly summary for pingcap/tidb-operator: Implemented a stability enhancement for volume replacement by introducing a pre-eviction step for TiKV leaders before replacement. This change addresses excessive CPU/IO usage when leaders remain active during replacement, reducing latency impact on clients and improving reliability of volume-management workflows. The fix is captured in commit e84b19cf93e787a4d3adc9de94d9004f1df944aa (referenced in #6069).
