remote_api documentation's example, batching on __key__ without ordering?

[Simo Salminen]

Hi.

In http://code.google.com/appengine/articles/remote_api.html there is
example:

entities = MyModel.all().fetch(100)
while entities:
for entity in entities:
# Do something with entity
entities = MyModel.all().filter('__key__ >', entities[-1].key
()).fetch(100)


How come there is no ordering on __key__?

[Dan Sanderson]

__key__ is the default ordering when no other filters or sort orders are requested.  (In general, __key__ is the last ordering applied after all other orders.)
