Many parts of MediaWiki assume that the DB is "close by and secure", which will change for Multi-DC. How do we address this?

Long term, what do we do with MYSQL? It doesn’t do master-master operations and blocks us from supporting writes in both locations.

If we remove performance tricks in MediaWiki, would the performance be acceptable and enable us to generalize the DB abstraction? Working on the Abstract Schema Migrations RFC may clear some of this question up.
