Does DCS Manage Instances in Sentinel Mode?

  • Cluster instances, master/standby and read/write splitting 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 and the service will be resumed automatically.

    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 automatically.
