Is anyone using datacenter aware replication where the replication takes place over the wan and not over super fast optical cable between the centers?
Tried to look at all posts related to the topic but haven't really found too much, only some things about not doing that if using ZooKeeper and some other small comments. What are the limitations for this kind of replication, what happens when the writes are coming in too fast for the replication to be done, assuming some kind of write buffer for the replication? Not really worried too much about the inconsistent state of the cluster, just how well it would work is this kind of environment. -- Regards Erik
