Read directly from a replica inside Redis cluster

Question

I want to read directly from a replica inside a Redis cluster but I am getting redirected even if the key actually exist inside the Redis node.

Checked READONLY command docs. However, that is seemed to be ignored in case of Redis Cluster.

How should I configure the Redis cluster so that I can directly read from a replica node for the reads issue against its hash slots? I am OK to read stale data in this case.

The READONLY command (as well as the READWRITE command that counteracts it) are applicable per connection in a clustered environment.

While READWRITE is the default behavior, in order to change that you'll need to call READONLY in the context of the connection that you're using.
