the primary considerations are (1) being able to satisfy reads locally, without incurring cross-datacenter latency, and (2) failure scenarios. The two most common ways to configure multiple data center number of replicas per data center in a comma separated list of datacenter_name:number_of_replicas. Note that what you specify for datacenter_name depends on the cluster-configured snitch you are using.

On each node in the cluster, run nodetool repair for each keyspace that was updated
