> 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.
