Inter datacenter replication
I see a lot about setting up single clusters and some comments around running clusters across AV zones in AWS however I don't see anything about proper inter-datacenter replication.
Is there a way to have two separate clusters fully replicated?
For example, in separate AWS regions or between AWS and Joyent?
In the scenario where multiple hosts in a cluster are spread across AV zones, is there a way of ensuring that there's at least a copy of the data in each AV zone (without limiting the cluster size) and that hosts only retrieve from the local AV zone?
My concern is for Moxi deciding to do a cross-datacenter trip (even worse if it's from the US to Europe) and our response times going through the roof...
