      Description

      If metrics consumer is too slow to keep up processing received messages, eventually backpressure is triggered. Spout throttles, but metrics messages are not throttled so it could be chance for topology to be never back to normal.

      While STORM-1698 can resolve this issue, I made this issue to clarify this behavior and mark this as 'bug'.
