Hi experts, We have a cluster of 4 nodes across 2 data centers and we are using OldNetworkTopology to balance the replicas (RF=3).
Question: Can we afford to lose 1 node in a data center and still have Quorum work? My understanding is that OldNetworkTopology writes 2 to the "local" data center and "1" to the remote data center. If a node goes down, will cassandra switch to write 2 replicas to the remote data center and 1 to the local data center to compromise for the fact that there is only 1 local node alive? Or is writing 2 to local and 1 to remote a "do or die" situation? Thanks!
