Currently running a 3 node cluster with replication factor 3 on the keyspaces. Need to add more nodes to the cluster as the size of each node is approaching 2TB. Can I add just 1 more node to the cluster and have a 4 node cluster or does the cluster always need to have odd number of nodes? Using a consistency level of ONE currently for both read and write.
