Hi, We are using *apache storm 1.2.1*. We have spouts which keep polling queues which contain input messages for us. My question is, how can I delay my nextTuple() calls on the spout thread when there are no input messages available in the queue. Does storm provide an exponential backoff mechanism for such scenarios? If not, can I implement my own exponential backoff by calling org.apache.storm.utils.Utils.sleep() function? I am worried if ack() or fail() calls come on the spout thread when it is sleeping, can we face some sleep interrupted exceptions?
Thanks, Jayant Sharma
