GAE SDK 1.6.4 dev_appserver datastore flush

Question

Hoping to get a comment from the GAE python team on this one.

Has something changed between 1.6.3, 1.6.4 with regards to the way the dev_appserver datastore is flush

Answer 1

Before 1.6.4, we saved the datastore after every write. This method does not work when simulating the transactional model found in the High Replication Datastore (you would lose the last couple writes). It is also horribly inefficient. We changed it so the datastore dev stub flushs all writes and saves it's state on shut down.

Following the code:

1. https://bitbucket.org/wkornewald/djangoappengine/src/60c2b3339a9f/management/commands/runserver.py#cl-154
2. http://code.google.com/p/googleappengine/source/browse/trunk/python/google/appengine/tools/dev_appserver_main.py#683

It looks like manage.py should work if the server is shut down cleanly (with a TERM signal or KeyInterrupt).
