[jira] [Created] (FLINK-27263) Rename the metadata column to the user specified name in DDL

Shengkai Fang created FLINK-27263:
-------------------------------------

             Summary: Rename the metadata column to the user specified name in DDL
                 Key: FLINK-27263
                 URL: https://issues.apache.org/jira/browse/FLINK-27263
             Project: Flink
          Issue Type: Improvement
            Reporter: Shengkai Fang


Currently the source output the metadata column with the "$metadata"+ metadata key as the column name. It's better that keep the name align with the user name specified in the DDL,e.g. use event_time as the name if the user specifies`event_time` TIMESTAMP(3) FROM 'timestamp'.
