--------------------------------
Summary: Make worker receiver thread number configurable
Key: STORM-272
URL: https://issues.apache.org/jira/browse/STORM-272
Project: Apache Storm (Incubating)
Issue Type: Improvement
Affects Versions: 0.9.2-incubating
Reporter: Sean Zhong
Priority: Minor
In my profiling, I found the receiver thread of worker can be a performance
bottle-neck.
Now each worker has single receiver thread, and it is responsbile to transfer
information generated from multiple netty client to tens of executor disruptor
queue. It is too much for busy topology.
Without this fix, we have to increase the number of workers, which will create
more intra-worker traffic that we don't want.
