Client-Side Connection Resilience

Make clients survive failovers and topology changes with retries, timeouts, connection pools, and cluster-aware redirection handling.

HA Is a Two-Sided Deal

You configured replication, Sentinel, and Cluster on the server. But high availability only works if the client reacts correctly to failovers, moved slots, and dropped connections. This lesson covers client-side resilience.

Connection Pools

Opening a TCP connection per command is slow. A connection pool reuses a set of connections across requests, bounded by a maximum size to protect the server.

pool = redis.ConnectionPool(max_connections=50)
client = redis.Redis(connection_pool=pool)
