Yingjie Cao created FLINK-25786: ----------------------------------- 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 orderĀ 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. -- This message was sent by Atlassian Jira (v8.20.1#820001)
