It would probably be most efficient to use the Datastore together with the Memcache.
If you are new to all these things, I'd definitely recommend using the Objectify framework which completely trivializes the transfer of entities between GWT and GAE without having to use those awful DTOs. Objectify will also do all the Memcaching for you automatically. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
