-----------------------------------
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.
