I believe the only way to reset the datastore is to delete the application which might be an option if your site is not already live.

Otherwise you need to have the kind name to query for entities to delete by key (unless they all have a common ancestor). To get the available kind names you can use the meta-data api and then do a keys- only query on each.

If you have a large number of entities to delete you'll probably need to break the job up into tasks using cursors. The Deferred class is a great way to simplify this.

Hello everybody.

I want to gather the information about all the entities there are in
my Data Store, I need this in order to delete each one found. Does
anybody know how to do this? or is there any other way for deleting
all the entities in data store?  something like "RESET the whole data
Store"

Thanks.
