Dear list, I was wondering what is the best practice to do synchronization in storm or is it possible to have congestion collapse in Storm?
Say I have a spout-boltA-boltB topo and the boltB happen to be very slow. Bolt A is emitting data much faster than Bolt B can process. If I do nothing, will failure handling mechanism be triggered and Bolt A will put all things not acked to Bolt B again and further burden the system. Finally Bolt A become slow due to the accumulated queue and Spout A will trigger tuple retransmitting too and the whole system fails. Is that possible to happen? Thanks -Mo Dong
