I have a simple deployment in my local using minikube, where I deployed a redis sentinel using helm. That’s the configmap configuration related to RDB and AOF.
<code> # User-supplied common configuration:
# Enable AOF https://redis.io/topics/persistence#append-only-file
#appendonly yes
# Disable RDB persistence, AOF persistence already enabled.
#save 5 1
save ""
# End of common configuration
</code>
<code> # User-supplied common configuration:
# Enable AOF https://redis.io/topics/persistence#append-only-file
#appendonly yes
# Disable RDB persistence, AOF persistence already enabled.
#save 5 1
save ""
# End of common configuration
</code>

# Enable AOF https://redis.io/topics/persistence#append-only-file
#appendonly yes
# Disable RDB persistence, AOF persistence already enabled.
#save 5 1
save ""
# End of common configuration
As you can see RDB is disabled as well as AOF.
Here are the sentinel instances of Redis, 1 master 2 worker.
<code>NAMESPACE NAME READY STATUS RESTARTS AGE
default redis-node-0 2/2 Running 0 16m
default redis-node-1 2/2 Running 0 15m
default redis-node-2 2/2 Running 0 14m
</code>
<code>NAMESPACE NAME READY STATUS RESTARTS AGE
default redis-node-0 2/2 Running 0 16m
default redis-node-1 2/2 Running 0 15m
default redis-node-2 2/2 Running 0 14m
</code>

When I exec into redis-node-0 I see nothing inside /data directory, as I expected.
However, for redis-node-1 and redis-node-2 there are dump.rdb files within the /data directory.
Why it is the case? I though I disabled snapshot feature totally.
It behaves like that because this is redis sentinel?
