Dear Everyone, We are running Cassandra v2.0.15 on our production cluster.
We would like to reduce the replication factor from 3 to 2 but we are not sure if it is a safe operation. We would like to get some feedback from you guys. Have anybody tried to shrink the replication factor? Does "nodetool cleanup" get rid of the replicated data no longer needed? Thanks in advance for your support. Regards, Alessandro
