> > Hi Jeff,
Actually my requirement is that , Whenever I save a new entity, the id field should get autogenerated. If I have to do it on my own (as you suggested DatastoreService.allocateIds()), how do we handle scenarios like two threads on different machines trying to store the newly created entites in the datastore (thereby trying to assign different ids). I am not well versed with all the concepts. If you can please elaborate, that would be really useful. And you are right in guessing that I need the shortest possible value. Hashes, I suppose are not guaranteed to be unique for two different arbitrary strings. Thanks, -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
