-----------------------------------

             Summary: Increase the default value of taskmanager.network.sort-shuffle.min-buffers
                 Key: FLINK-22305
                 URL: https://issues.apache.org/jira/browse/FLINK-22305
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Network
            Reporter: Yingjie Cao
             Fix For: 1.13.0


Currently, the default value of taskmanager.network.sort-shuffle.min-buffers is 64, which is pretty small. As suggested, we'd like to increase the default value of taskmanager.network.sort-shuffle.min-buffers. By increasing the default taskmanager.network.sort-shuffle.min-buffers, the corner case of very small in-memory sort-buffer and write-buffer can be avoid, which is better for performance.
