Yingjie Cao created FLINK-25860: ----------------------------------- Summary: Move read buffer allocation and output file creation to setup method for sort-shuffle result partition to avoid blocking main thread Key: FLINK-25860 URL: https://issues.apache.org/jira/browse/FLINK-25860 Project: Flink Issue Type: Sub-task Components: Runtime / Network Reporter: Yingjie Cao Fix For: 1.15.0
Currently, the read buffer allocation and output file creation of sort-shuffle is performed by the main thread. These operations are a little heavy and can block the main thread for a while which may influence other RPC calls including follow-up task deployment. This ticket aims to solve the issue by moving read buffer allocation and output file creation to setup method. -- This message was sent by Atlassian Jira (v8.20.1#820001)
