Jonathan Ellis resolved CASSANDRA-2338.
---------------------------------------
Resolution: Won't Fix
I don't think this is actually feasible.
> C* consistency level needs to be pluggable

> Key: CASSANDRA-2338
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2338
> Project: Cassandra
> Issue Type: New Feature
> Reporter: Matthew F. Dennis
> Priority: Minor
>
> for cases where people want to run C* across multiple DCs for disaster
> recovery et cetera where normal operations only happen in the first DC (e.g.
> no writes/reads happen in the remove DC under normal operation) neither
> LOCAL_QUORUM or EACH_QUORUM really suffices.
> Consider the case with RF of DC1:3 DC2:2
> LOCAL_QUORUM doesn't provide any guarantee that data is in the remote DC.
> EACH_QUORUM requires that both nodes in the remote DC are up.
> It would be useful in some situations to be able to specify a strategy where
> LOCAL_QUORUM is used for the local DC and at least one in a remote DC (and/or
> at least in *each* remote DC).
