The sentinel stores hardcoded a 30s read timeout and a 1m retry backoff. After a sentinel failover every request that picked a pooled connection to the old master sat there for 30s before the connection was retired, and the pool timeout derived from it (read timeout + 1s) queued the rest behind them. The other redis stores took the go-redis defaults with no way to tune anything. Read the dial, timeout and pool knobs from each redis store section instead, keeping the go-redis default for every key left unset.
