Yingjie Cao created FLINK-20740: ----------------------------------- Summary: Use managed memory to avoid direct memory OOM error Key: FLINK-20740 URL: https://issues.apache.org/jira/browse/FLINK-20740 Project: Flink Issue Type: Bug Components: Runtime / Network Affects Versions: 1.12.0 Reporter: Yingjie Cao Fix For: 1.13.0
Currently, sort-merge blocking shuffle uses some unmanaged memory for data writing and reading, which means users must increase the size of direct memory, otherwise, one may encounter direct memory OOM error, which is really bad for usability. -- This message was sent by Atlassian Jira (v8.3.4#803005)
