> After [a survey on the dev mailing list|http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/SURVEY-Dropping-non-Credit-based-Flow-Control-td33714.html] the feedback was that old code path is not used and no longer needed. Based on that we should be safe to drop it and make credit based flow control the only option (currently it's the default).
