(Get the code!)
As if it was not enough db sync is not idempotent with mysql (DDL is *not* transactional in mysql).
Thus a failed db sync leaves the cluster in a badly broken state. Recovering from such a state
requires manual inspection of tables and selectively running DB migration scripts to add missing tables, columns, constraints, etc.
This is not a big deal for a new deployment (one can wipe out all tables and start over),
however this is a real disaster for upgrades.
