+## Redis Sentinel behavior
+
+Use `redisType: "node"` when connecting to Redis Sentinel. Additionally, set `failover` to `"true"` and `sentinelMasterName` to the name of the master node.
+
+Failover characteristics:
+- Lock loss during failover: Locks may be lost during master failover if they weren't replicated to the promoted replica before the original master failed
+- Failover window: Brief server unavailability (typically seconds) during automatic master promotion  
+- Consistency: All operations route to the current master, maintaining lock consistency
+
+{{% alert title="Warning" color="warning" %}}
+Consider the trade-off of running Redis with high-availability and failover with the potential of lock loss during failover events. Your application should tolerate brief lock loss during failover scenarios.
