Does DCS Support Sentinels?

Redis 4.0 and later:

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 and sentinel-without-auth parameter is enabled. For details about how to enable parameter cluster-sentinel-enabled, see Modifying Configuration Parameters of an Instance.

Parameter sentinel-without-auth is currently whitelist-based. By default, it is not displayed for Proxy Cluster instances. To configure it, contact customer service.

Redis 3.0 instances do not support Sentinels.
