---------------------------------------
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.
