Question

How can I get all entity kinds from GAE server?
Is this possible?
I want to make a DB manager tool for GAE.

The best way to do this is to programmatically read the datastore stats. See the docs for doing so in Python or Java. Here’s a simple example in Python:

>>> from google.appengine.ext.db import stats
>>> kinds = stats.KindStat.all().fetch(1000)
>>> kind_names = [x.kind_name for x in kinds]
>>> kind_names
[u'A', u'AAFoo', u'AModel', u'ASDBD', u'Abc', u'Accumulator', u'Activity', # ...

You can test this for yourself in the interactive console.

The datastore stats also provide piles of other details that will be useful in writing a datastore management tool. Good luck!
