-// TODO(fspreck) One possibility for count-queries: Transaction gets a
-// GetQueryCount function that returns exactly this. In case of a
-// single FIND Query this will be equivalent to the Size of the
-// ResultSet, but it may be different in case of Query + RetrieveById,
-// and in case of COUNT queries which have an empty ResultSet. We have
-// to think about how to extend this to transactions with more than
-// one query in the future. My suggestion is to treat a transaction
-// with more than one query as the union of the query results in which
-// case the query count would return the cumulative number of
-// results. This would even allow the combination of FIND, FIND
-// unique, and COUNT, albeit a little strangely.
