we have a simple cluster consisting of only 3 Cores.
On intensive WRITE operations, we observe significant CPU load on only one of the nodes, which is Leader. Which is OK I guess since only a Leader receives writes and communicates them to the others.
However, on intensive READ operations, the behaviour is similar - only Leader is loaded.
So my question is (I could not find a clear explanation of it in the docs) - should READ operations be load-balanced between all members if a cluster consists of only COREs, i.e. does not contain any READ_REPLICAs?
We tried to enable this in the configuration, but to no avail:
