It appears that the spouts across all the workers are throttled if an
executor queue fills up. For instance if there are multiple spouts, even the
ones not causing the executor recv queue to fill would be throttled. Is this
correct and if so desirable?
Wont it be ideal to trickle the back pressure up via the immediately
preceding component(s) than slowing down the entire topology ?
