Jonathan Ellis commented on CASSANDRA-4285:
-------------------------------------------
We'd also want to restrict the DCL to nodes in the same datacenter. No sense
in sending this data over the WAN. Since ReplicationStrategy only depends on
the partition key, not the coordinator location, we probably need to do
something sneaky like having a strategy that generates N replicas in each DC,
then special case the DCL in StorageProxy to ignore replicas outside the
coordinator's DC.
