[jira] [Created] (FLINK-27541) Support distribute by For FlinkSql

Aiden created FLINK-27541:
-----------------------------

             Summary: Support distribute by For FlinkSql
                 Key: FLINK-27541
                 URL: https://issues.apache.org/jira/browse/FLINK-27541
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / Planner
            Reporter: Aiden


Now we cann't add a shuffle-operation in a sql-job.
Sometimes , for example,  I have a kafka-source(three partitions) with parallelism three. And then I have a lookup-join function, I want process the data distribute by id so that the data can split into thre parallelism evenly (The source maybe slant seriously).  In DataStream API i can do it with keyby(),  but it's so sad that i can  do nothing when i use a sql;
