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

             Summary: Consider removing UnknownInputChannel in NettyShuffleEnvironment
                 Key: FLINK-13641
                 URL: https://issues.apache.org/jira/browse/FLINK-13641
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Network
            Reporter: Andrey Zagrebin


UnknownInputChannel basically is a place holder while the producer is unknown which contains some partition parameters to use later for creation of the known channel.

If NettyShuffleEnvironment#updatePartitionInfo provides enough information to add the known channel, one could consider removing UnknownInputChannel and refactoring indexed channel array into a dynamic list.

Initially suggested in [https://github.com/apache/flink/pull/8362#discussion_r290308989]
