Subject How do you tune the parallelism number of each bolt?
Date Wed, 03 Aug 2016 02:36:21 GMT
Hi everyone,

I find it seems the performance of topology doesn’t increase as the increasing of parallelism
number of bolt. Sometimes the capacity decreases and execute latency becomes faster when I
set the parallelism hint to a lower value.  So how do you tune the parallelism hint?
