Yingjie Cao created FLINK-21778: ----------------------------------- Summary: Use heap memory instead of direct memory as index entry cache for sort-merge shuffle Key: FLINK-21778 URL: https://issues.apache.org/jira/browse/FLINK-21778 Project: Flink Issue Type: Sub-task Components: Runtime / Network Affects Versions: 1.12.0 Reporter: Yingjie Cao Fix For: 1.13.0
Currently, the sort-merge shuffle implementation uses a piece of direct memory as index entry cache for acceleration. We can use heap memory instead to reduce the usage of direct memory which further reduces the possibility of OutOfMemoryError. -- This message was sent by Atlassian Jira (v8.3.4#803005)
