This triggers the evict-leader scheduler to restore performance when a slow node is identified. -- **Unified health controller**: adds a unified health controller in TiKV and a feedback mechanism to the KV-client. The KV-client optimizes error handling and replica selection based on TiKV node health and performance. -- **Improved replica selector**: introduces Replica Selector V2 in the KV-client, with refined state transitions that eliminate unnecessary retries and backoff operations. -- **Additional fixes and improvements**: includes enhancements to critical components such as the region cache and KV-client health checker, while avoiding unnecessary IO operations in TiKV's store loop. +- **Unified health controller**: adds a unified health controller in TiKV and a feedback mechanism to the KV client.
