[google-appengine] Error while Deleting all entities in the namespace

2012-09-18 Thread Aswath Satrasala 
Hi,
I am struggling to clear up my unused namespaces.  The datastore admin
console does not provide this feature.

I am using the following code.  This is assumed that the namespace has few
entities, and hopefully will execute with in the 1min appengine time limit.

String oldNamespace = NamespaceManager.get();
try {
  NamespaceManager.set(namespaceToDelete);
  DatastoreService ds = DatastoreServiceFactory.getDatastoreService();
  Query q = new Query().setKeysOnly();

  final ArrayListcom.google.appengine.api.datastore.Key keys =
new ArrayListcom.google.appengine.api.datastore.Key();

  for (final Entity entity: ds.prepare(q).asIterable()) {
   keys.add(entity.getKey());
  }
  ds.delete(keys);
} finally {
  NamespaceManager.set(oldNamespace);
}


*
*
*I get the following error*
*illegal key.path.element.type: __Stat_Ns_Kind_CompositeIndex__*

Any pointers will be appreciated.

Don't try to delete anything with __ at the beginning; those are GAE
special administrative kinds.
