Hi Gyula, even after trying different things, I can't seem to get the hold of things. Also, i asked another question on the working of iteration and streaming here <http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Unexpected-behaviour-in-datastream-broadcast-td6848.html>
Because its not working the way i am expecting it to be and the inputstream is completely consumed before anything is sent back and iterated. Could you please send me to a proper direction and help me in understanding the things properly?
