Hi , So I have a situation where I want to read messages from different queues hosted in a Rabbitmq Server .
Now , there are three ways which I can think to leverage Apache Storm here :- 1) Use the same Spout (say Spout A) to read messages from different queues and based on the messages received emit it to different Bolts. 2) Use different Spout (Spout A and Spout B and so on) within the same topology (say Topology A) to read messages from different queues . 3) Use Different Spouts one within eachTopology (Topology A , Topology B and so on) to read messages from different queues . Which is the best way to process this considering I want high throughput (more no of queue messages to be processed concurrently) . Also , If In use same Topology for all Spouts (currently though requirement is for 2 spouts) will failure in one Spout (or its associated Bolts) effect the second or will they both continue working separately even if some failure is in Spout B ? Cost wise , how much would it be to maintain two different topologies . Looking for inputs from members here. Thanks Ankur
