> Currently, for sort-shuffle the generation of subpartition data storage order
> is random shuffle. However, if there is no enough resources to run the
> downstream consumer tasks in parallel, the performance can be influenced
> because of the random disk IO caused by the random subpartition data storage
> order. This ticket aims to improve this scenario.
