Description

We can issue direct SQL queries to drop e.g. partitions to speed things up; as is the usual approach with direct SQL, having a fully functional fallback to datanucleus.
One thing to consider is whether we could mess with DN if we do that, invalidating some of its assumptions and breaking code accessing the underlying datastore via DN on other threads.
