How to delete all datastore in Google App Engine?

Question

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

Answer 1

There are several ways you can use to remove entries from App Engine's Datastore:

1. First, think whether you really need to remove entries. This is expensive and it might be cheaper to not remove them.

2. You can delete all entries by hand using the Datastore Admin.

3. You can use the Remote API and remove entries interactively.

4. You can remove the entries programmatically using a couple lines of code.

5. You can remove them in bulk using Task Queues and Cursors.

6. Or you can use Mapreduce to get something more robust and fancier.

Each one of these methods is explained in the following blog post: http://www.shiftedup.com/2015/03/28/how-to-bulk-delete-entries-in-app-engine-datastore
