Subject Storm DRPC topology performance problem
Date Wed, 06 Sep 2017 14:52:32 GMT
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
