Redis - Total Keys in Cluster

Question

I want to check total number of keys in Redis Cluster.

Is there any direct command available to get this or I have to check with INFO command from each instance / node.

Answer 1

There is no direct way.

You can do the following with the cli though:

redis-cli --cluster call one-cluster-node-ip-address:the-port DBSIZE

And then sum the results.

Alternatively, there's RedisGears with which you can do the following to get the same result:

redis> RG.PYEXECUTE "GB().count().run()"
