Hello, I have a question regarding direct streaming and sending a tuple from a downstream node to its upstream node. To be more precise, let us assume we have the following topology:
Spout-1 --(direct-grouping)--> Bolt-1 --(direct-grouping)--> Bolt-2 Can Bolt-2 call emitDirect() and send a tuple back to Bolt-1 (by getting the task-id from tuple.getSourceTask() )? If not, is it because of the general architecture of Storm? Thanks, Nick
