Now that Redis Cluster comes with sharding, replic

问题:

Now that Redis Cluster comes with sharding, replication and automatic failover, do i still need to use Sentinel for failover handling ?

回答1:

No. Sentinel is for managing the availability and providing service discovery when using Redis in single instance mode (single-master/one-or-more-slaves). When using Redis in cluster mode, Sentinel isn't needed.
