Thanks, Jason - you guys have been supporting the community wonderfully. I have a question: I see there is a get(Iterable<Key> keys), that only returns entities that exist (i.e. doesn't throw an exception when an entity isn't found). This looks like it could be really useful, e.g. as an IN query. Is there a 'reasonable' maximum to the amount of keys you can put in? E.g. 20, 100, 500?
