> 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.
