Understanding Sentinel Cluster Rate Limiting and Handling Network Jitter
Sentinel’s cluster rate limiting adds a centralized token server that grants tokens to client instances before processing requests, and when network jitter causes request timeouts the client automatically falls back to local limiting, so configuring short request‑timeout values (e.g., 20 ms) is crucial for maintaining low latency and high availability in elastic, multi‑instance deployments.
