[jira] [Created] (FLINK-28378) Use larger data reading buffer size for sort-shuffle

Yingjie Cao created FLINK-28378:
-----------------------------------

             Summary: Use larger data reading buffer size for sort-shuffle
                 Key: FLINK-28378
                 URL: https://issues.apache.org/jira/browse/FLINK-28378
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Network
            Reporter: Yingjie Cao
             Fix For: 1.16.0


Currently, for sort shuffle, we always use the network buffer size as the data reading buffer size which is 32K by default. We can increase this buffer size for better performance.
