Github user HeartSaVioR commented on the pull request: https://github.com/apache/storm/pull/532#issuecomment-156864048 @revans2 Oh, I have been forgotten TOPOLOGY_SHELLBOLT_MAX_PENDING when creating this PR. I agree that we would be fine with TOPOLOGY_SHELLBOLT_MAX_PENDING since it guarantees count of pending tuples with blocking manner, and finally ABP would be triggered when subprocess couldn't handle tuples as fast as it flows. Btw, do we have to take care of ABP when TOPOLOGY_SHELLBOLT_MAX_PENDING is off?
