-----------------------------------
Summary: Adjust the generation of subpartition data storage order
for sort-shuffle from random shuffle to random shift
Key: FLINK-25786
URL: https://issues.apache.org/jira/browse/FLINK-25786
Project: Flink
Issue Type: Sub-task
Components: Runtime / Network
Reporter: Yingjie Cao
Fix For: 1.15.0
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.
