Do DCS Clients Support Sentinels?
Single-node, master/standby, and Redis Cluster instances do not support Sentinels.
Read/Write splitting instances support Sentinels and clusters.
For Proxy Cluster instances, clusters are supported by default, Sentinels are supported after the cluster-sentinel-enabled parameter is enabled. For details about how to enable parameter cluster-sentinel-enabled, see Modifying Configuration Parameters of an Instance.
