Yingjie Cao created FLINK-20758: ----------------------------------- Summary: Use region file mechanism for shuffle data reading before we switch to managed memory Key: FLINK-20758 URL: https://issues.apache.org/jira/browse/FLINK-20758 Project: Flink Issue Type: Sub-task Components: Runtime / Network Affects Versions: 1.12.0 Reporter: Yingjie Cao Fix For: 1.12.2
FLINK-15981 implemented region file based data reader to solve the direct memory OOM issue introduced by usage of unmanaged direct memory, however only for BoundedBlockingResultPartition. We can introduce it to sort-merge based blocking shuffle to avoid the similar direct memory OOM problem which can improve the usability a lot. -- This message was sent by Atlassian Jira (v8.3.4#803005)
