Hi, a globally shared state is not supported by Storm. This is true, for many (maybe even all?) large-scale distributed systems, because a shared global stated does not scale!
However, if you just want to know the number of processed tuples, you do
not need a globally shared state. Actually, Storm's UI maintains
counters and you can also access those counters in your application via
> Client.getTopologyInfo("topology-id");
