> Partition reuse is a very useful optimization in some topologies. In essence,
> multiple downstream tasks consume the same subpartition's data. Therefore,
> hybrid shuffle should also enjoy the benefits it brings. After FLINK-28889,
> we are finally able to achieve repeated consumption at the subpartition level
> for hybrid full spilling strategy, so let's make it better.
