PROFILE
Bo Liu
Over a three-month period, Liubo contributed to the pingcap/tidb-operator repository by developing features that enhanced cluster stability, observability, and operational reliability. He implemented a proactive leader eviction mechanism for TiKV scale-in, using Go and Kubernetes APIs to sequence leader evictions with timeouts before store deletions, reducing disruption during scaling. Liubo also introduced sidecar log tailing support via CRD changes, enabling centralized log collection and simplifying troubleshooting. Additionally, he added a configurable log flush delay after SIGTERM, updating both the operator logic and CRDs using Go and Shell scripting to ensure complete log capture during graceful shutdowns and upgrades.

Jun 1, 2025June 2025 – Key delivery: TiKV Scale-In Stability: Proactive Leader Eviction for tidb-operator. Implemented a timeout and sequencing mechanism to evict TiKV leaders before deleting stores during scale-in, ensuring leaders are evicted or timed out prior to deletion, which improves cluster stability and reliability during scaling events. Commit: 97187a726662333415c8a757832623bd96b04868 (feat(tikv): try to evict leaders before deleting stores (#6239)).
