Carl Steinbach commented on HIVE-2147:
--------------------------------------

Yes, that's pretty much my definition of events vs. RPCs. How do you define it?

One advantage of this definition is that it's explicit that event generators 
don't have to block waiting for a response from a listener. Another advantage 
is that it's compatible with the model where multiple listeners can handle each 
event since there's no need to bundle a response from each of them (which also 
helps to cut down on latency).
