Does DCS for Redis Support Sentinels?

  • Cluster instances and master/standby DCS Redis 4.0, 5.0, and 6.0 instances support Sentinels. Sentinels monitor the running status of both the master and standby nodes of a master/standby instance and each shard of a cluster instance. If the master node becomes faulty, a failover will be performed.

    Sentinels are invisible to you and is used only in the service.

  • DCS for Redis 3.0 does not support Redis Sentinel. Instead, it uses keepalive to monitor master and replica nodes and to manage failovers.
