Howto clean database

There is no way to drop all tables. The best would probably to start the Interactive Console of your app engine and paste code like this:

from google.appengine.ext import ndb
from models import UserData
keys = UserData.query().fetch(keys_only=True)
ndb.delete_multi(keys)

and repeat that for each data model.

Atomic nbd.put()

Data objects are modified in the handlers and then all the modifications are sent to the storage together by NBD's put() method, which in itself is consistent. See https://developers.google.com/appengine/docs/python/storage : "Strongly consistent"

IPv6 compatibility

"This means that all App Engine apps will become accessible over IPv6 to anyone participating in the program!" http://googleappengine.blogspot.de/2010/03/app-engine-joins-google-over-ipv6.html

Data storage comparision

"Strongly consistent except when performing global queries." "The App Engine Datastore offers a free quota with daily limits. Paid accounts offer unlimited storage, read, and write operations." https://developers.google.com/appengine/docs/python/storage
