sure, there are various ways how to limit the data or split it into
chunks on the couchdb side. but sometimes it would be easier to just
say "hey give me everything you've got and i'll chew through it". I
run into these situations quite often when I neech to update all
documents (or a subset of documents) for whatever reason, and you only
can do that one by one in couchdb.
