Hey Guys,
We are using Storm DRPC topology to do some computational intensive work to respond to user queries in realtime. The topology contains 4 linear functions to handle user query, and returns query result to user through last function. Everything works fine when there are little queries at the same time, but when the parallelism goes higher, the response time for the DRPC topology gets much higher than before even if we increase the parallelism of each function and add more workers for the topology. Any suggestions on the performance tuning of this kind of topologies? Thank you! -- Mou Yanfei Tel: +86 15618965103
