i think there are already async datastore operations, although not yet documented. i'd love for you guys to check this out and tell me what you think
John Patterson uses async datastore calls in his twig-persist, see here: http://code.google.com/p/twig-persist/wiki/Using#Parallel_Asynchronous_Commands if you look at his source code AsyncDatastoreHelper (http:// code.google.com/p/twig-persist/source/browse/src/main/java/com/google/ appengine/api/datastore/AsyncDatastoreHelper.java) he uses an async call: static Future<byte[]> makeAsyncCall(String method, ProtocolMessage<?> request) { try { return ApiProxy.makeAsyncCall("datastore_v3", method, request.toByteArray()); } catch (ApiProxy.ApplicationException exception) { throw DatastoreApiHelper.translateError(exception); } } The only other code I found using ApiProxy.makeAsyncCall was Max Ross in http://code.google.com/p/datanucleus-appengine/source/browse/trunk/tests/org/datanucleus/store/appengine/query/NoQueryDelegate.java?spec=svn412&r=412 If someone wants to take a stab at it and explain how to use those low- level calls that would be fantastic!
