Hi Everyone,

When you move to the 1.7.5 SDK, consider trying out the new automatic ID 
allocation policy option in the dev appserver. You can now have your local 
datastore assign scattered auto IDs.

See the docs on "Specifying the Automatic ID Allocation Policy":
https://developers.google.com/appengine/docs/Python/tools/devserver#Using_the_Datastore<https://developers.google.com/appengine/docs/java/tools/devserver#Using_the_Datastore>
https://developers.google.com/appengine/docs/java/tools/devserver#Using_the_Datastore

The dev appserver ID policy will default to "scattered" in the next 
release. It's a good idea to try it out now to ensure your tests aren't 
relying on sequential IDs.

Also, as always, your apps should make no assumptions about automatic ID 
ordering in production. Automatic IDs have never been predictable in 
production.

Questions welcome!

Thanks,

Jesse Rohwer
