GAE: Best way to determine how many of a Kind is stored?
If you do keys-only it should be pretty fast, since this only has to read the index and doesn't actually fetch any entities. Use a cursor and loop until count() returns less than 1000.
What is the best way to determine how many models of a certain kind are in my app's datastore? The documentation says that MyKind.all().count() is only marginally better than retrieving all of the data, and has a limit of 1000. This is not helpful, because I am expecting to have 6000+ instances of MyKind stored.
Is there a better way to do this? What if I just get  the keys, and count those?
I'm using Python.
