You might be confusing the RackAware strategy (which puts 1 replica in a remote DC) and the DatacenterShard strategy (which puts M of N replicas in remote DCs). Both are in 0.6.5.

Is there any plan to backport DataCenterShardStrategy to 0.6.x from 0.7? It will be very useful for those who don't want to make drastic changes in their code and get the benefits of this replica placement strategy. -- Thanks, -rbukshin
