Hi, I've wanted to do this and this post confirms the idea: http://stackoverflow.com/a/36106683/453673 But when I have a spout that constantly has nextTuple() being called by Storm and I have a bolt that constantly has execute() being called whenever it receives a tuple, how do I program the Spout to have a separate thread which reads from MongoDB or for the bolt to have a separate thread that writes to DB?
If Storm is in complete charge of calling nextTuple() and execute(), then how do I start my own thread which does something? This is important, because I don't want my bolt to spend time writing to DB, when it should actually be busy receiving and processing hundreds of tuples. -- Regards, Navin
