> Right now tunable consistency allows for things like local quorum and each quorum across multiple datacenters.
> I propose something in between where you achieve local quorum + 1 node at other DC. This would make sure the data is written to the other datacenter for resilience purposes but be better performing that having to do an each quorum write at both datacenters. Mind you re-reviewing each_quorum I'm not sure how much more performant this would be...
