In general, it is also recommended to use later versions of Redis version 2.8 in production environment. Sentinel is a distributed system. You can run multiple sentinel processes in one architecture. These processes use gossip protocols to receive information about whether the Master master server is offline, and use Agreement Protocols to decide whether to perform automatic failover and which Slave to select as the new Master.

English name: Subjective Down, SDOWN for short. Subjective Down,
