--------------------------------------

             Summary: Remove non credit based network code
                 Key: FLINK-14516
                 URL: https://issues.apache.org/jira/browse/FLINK-14516
             Project: Flink
          Issue Type: Task
          Components: Runtime / Network
    Affects Versions: 1.9.0
            Reporter: Piotr Nowojski


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. Because of that we should be safe to drop it and make credit based flow control the only option (currently it's the default).
