Hey all, We're testing Cassandra failover over 2 Datacentre's.
There are 3 nodes on each. All CF's have a Replication of 2 on both Datacentre's (DC1:2, DC2:2) When one Datacentre goes down then all queries go to the other. This works fine for LOCAL_QUOURM queries. As 2 replicas of the data exist in this Datacentre. However in the scenario where the 2 Datacentre's are up and one node goes down, all queries to that Datacentre will fail for LOCAL_QUOURM This is because the node that failed had the replica data, and there is only 1 remaining node with the data. So LOCAL_QUOURM which requires 2 nodes with replica data will fail Is there a way to not send these queries to the incomplete Datacentre. What the best way the handle this?
