THANK YOU Luis!! :) That is what I needed. Let's imagine that I have just one stream run in one JVM. Do you know how many futures will be evaluated and wait for completion? You know, I can not have billion of futures in memory :/. Will this be auto-regulated by back pressure of if not then where I can configure maximal number of futures?
