Hi Everyone, During the course of profiling (actually sampling) a worker process with jvisualvm I noticed the executor and worker zk send threads are always active. I then checked the heartbeat settings on my topology and noted that the default executor heartbeat is 1 second.
Question: is this a potential performance bottleneck? Would it make sense to bump this up to 5 or 10 seconds? Would like to see what y'all think. Thanks --John
