Without the MaxWait being set to 100, it is set to 10000, which means that
the bolt will waiting for 10 seconds when no messages are available. On the 1.x
branch, I was going to use:
+ public int fetchMaxWait = FetchRequest.DefaultMaxWait();
+ public int fetchMinBytes = FetchRequest.DefaultMinBytes();
to get Kafka default behavior of 100/1.
