             Summary: Support to define an existing field as the rowtime field for TableSource
                 Key: FLINK-7446
                 URL: https://issues.apache.org/jira/browse/FLINK-7446
             Project: Flink
          Issue Type: Improvement
          Components: Table API & SQL
            Reporter: Jark Wu


Currently {{DefinedRowtimeAttribute}} can define an appended rowtime field for a {{TableSource}}. But it would be helpful if we can support to define an existing field as the rowtime field. Just like registering a DataStream, the rowtime field can be appended but also can replace an existing field.
