google app engine - Objectify async: at what point RPC call is made? -

quite want make 2 or more independent queries fetch entities datastore. i'm not sure if parallel. example: loadresult1 = ofy().load().key(key.create(foo.class, 1)); loadresult2 = ofy().load().key(key.create(bar.class, 1)); loadresult1.now(); loadresult2.now(); is there benefit of arranging code this? same goes search queries iterable1 = ofy().load().type(foo.class).iterable(); iterable2 = ofy().load().type(bar.class).iterable(); iterable1.hasnext(); iterable2.hasnext(); will iterable2 load in parallel iterable1? side question: .iterable() in regard different .list() ? i tried debug code, doesn't call made until call .now() , or first call .next()/.hasnext() in. so? yes - until materialize result, queries proceed asynchronously in parallel.
