@john thanks I'll try that but I'm asking also about other properties , in what conditions I should change of default values , and is max.spout.pounding is related to tweets that I set it in the code to emit it ? I mean if I set to get 500 tweets then I should set max.spout.pounding=500 Sorry for my lot questions but thanks for your helping .
