--------------------------------
> Introduce separate classes for PipelinedResultPartition and

> Key: FLINK-19046
> URL: https://issues.apache.org/jira/browse/FLINK-19046
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Network
> Reporter: Stephan Ewen
> Assignee: Stephan Ewen
> Priority: Major
> Fix For: 1.12.0
>
>
> Currently, the SubPartition classes are specific to the partition type
> (pipelined, batched/blocking) but the parent Partition class is shared.
> Given that the partitions behave differently regarding checkpoints,
> releasing, etc. the code is cleaner separated by introducing dedicated
> classes for the {{ResultPartitions}} based on the type.
> This is also an important preparation to later have more different
> implementations, like sort-based shuffles.
> Important: These new classes will not override any performance critical
> methods (like adding a buffer to the result). They merely specialize certain
> behaviors around checkpointing and cleanup.
