ok, i wanted to be sure about this, as pulling all the records and
just returning one would have been a performance disaster for my app.
my question was raised because i was a little surprised to read that
offset queries still pull all the 'upto' offset out of the store.
does the same apply to Thing.all().filter('value >' x).get() ?
and thus is it possible to page without pulling all the previous pages
data from the store each time?
