There's no difference. Both key_name's and id's are used internally to
build a Key from path, which is then used to get the entity. So, when
you do Model.get_by_id(1) or Model.get_by_key_name('a'), you're
actually doing Model.get(Key.from_path('Model', 1)) or
Model.get(Key.from_path('Model', 'a')) - essentially the same thing.
