Hi all, I want to add a data-center to an existing single data-center cluster. First I have to make the existing cluster multi data-center compatible.
The existing cluster is a 12 node cluster with: - Replication factor = 3 - Placement strategy = SimpleStrategy - Endpoint snitch = SimpleSnitch If I change the following: - Placement strategy = NetworkTopologyStrategy - Endpoint snitch = PropertyFileSnitch -> all 12 nodes in this file belong to the same data-center and rack. Do I have to run full repairs after this change? Because the yaml file states: IF YOU CHANGE THE SNITCH AFTER DATA IS INSERTED INTO THE CLUSTER, YOU MUST RUN A FULL REPAIR, SINCE THE SNITCH AFFECTS WHERE REPLICAS ARE PLACED. Thanks! Rene
