> For many datastore backends there's an optimized way of doing lookups by ID. For instance by using "Get" instead of "Scan" in HBase.
> For all the subclasses of PostprocessDataContext we should have a method that they can optionally implement, and thereby easily plug in such a lookup mechanism without too many query-inspection hurdles.
> A solution was already posted and accepted in review board (applied so far to MongoDB and HBase modules):
