--------------------------------------------------------------
Our internal use case is for HASH_ALL so I'm fine with not doing HASH and LOCAL.
I'll add a check for this and throw some exception if we try to set it for the
others.

> writes when the destination subcluster is down. We need an option to allow
> writing in other subclusters when one is down.
