I imagine that if you can afford clusters in multiple datacenters then
you should be able to afford EnterpriseDS. Or is it prohibitively
I have no idea. But afaics that's Basho's revenue model.

Replication will automatically propagate writes in both directions and will give you the local access performance you need. We recommend against having a single cluster span data centers as any given cluster really needs to share a low-latency network.
