How to delete all datastore in Google App Engine?

Question

Does anyone know how to delete all datastore in Google App Engine?

Answer 1

For Python, 1.3.8 includes an experimental admin built-in for this. They say: "enable the following builtin in your app.yaml file:"

builtins:
- datastore_admin: on

"Datastore delete is currently available only with the Python runtime. Java applications, however, can still take advantage of this feature by creating a non-default Python application version that enables Datastore Admin in the app.yaml. Native support for Java will be included in an upcoming release."
