Hey, How do you ensure, once you have queried an object from the datastore, that another call to that object cannot be made? I basically have a bunch of objects with counters which get incremented during each call to that object.
What I need to ensure is the object doesn't get called by two threads, each of which increment the counter by 1 and persist the object back to the datastore, only for the counter to be incremented by 1 and not by 2.
