[jira] [Created] (FLINK-15006) Add option to close shuffle when dynamic partition inserting

Jingsong Lee created FLINK-15006:
------------------------------------

             Summary: Add option to close shuffle when dynamic partition inserting
                 Key: FLINK-15006
                 URL: https://issues.apache.org/jira/browse/FLINK-15006
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / Planner
            Reporter: Jingsong Lee
             Fix For: 1.11.0


When partition values are rare or have skew, if we shuffle by dynamic partitions, will break the performance.

We can have an option to close shuffle in such cases.
