Chia-Ping Tsai commented on KAFKA-10126:
----------------------------------------
> What's about numFetchersOpt? Can it be removed?
I grep the code and both of numThreadsOpt and numFetchersOpt are indeed unused.
Removing them should be fine as it does not break the compatibility. However, I
prefer to make them work again.
> It seems that the topic could be created by the producer or kafka-topics.sh.
> So is it proper to add new arguments to create topic ?
If you have a KIP to explain the purpose of new arguments, it is ok to add new
arguments/behavior to ConsumerPerformance. At any rate, this can be discussed
in another issue.
