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

             Summary: ReaultPartitionWriter should not expose subpartition but only subpartition-readers
                 Key: FLINK-19087
                 URL: https://issues.apache.org/jira/browse/FLINK-19087
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Network
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 1.12.0


The {{ResultPartitionWiter}} currently gives arbitrary access to the sub-partitions.

These subpartitions may not always exist directly, such as in a sort based shuffle.
Necessary is only the access to a reader over a sub-partition's data (the ResultSubpartitionView).

In the spirit of minimal scope of knowledge, the methods should be scoped to return readers, not the more general subpartitions.
