Evolution of Envoy as a Dynamic Redis Proxy
summary
Envoy’s Redis proxy implements the Redis Cluster protocol, a Redis-specific load balancer and health checker, cluster-slots discovery plus a redirection manager, and multicluster prefix routing to enable zero application code changes for migrations. Production migrations move millions of QPS (largest deployments report ~23 million QPS across many nodes and clusters up to 500 nodes) using a mirror policy and reverse mirror approach; topology updates create temporary hosts and the system reports no outages so far thanks to careful validation.
