[jira] [Created] (FLINK-36854) Column comments and default expressions gone after being transformed

yux created FLINK-36854:
---------------------------

             Summary: Column comments and default expressions gone after being transformed
                 Key: FLINK-36854
                 URL: https://issues.apache.org/jira/browse/FLINK-36854
             Project: Flink
          Issue Type: Bug
          Components: Flink CDC
    Affects Versions: cdc-3.2.1
            Reporter: yux


Currently, transform operator will swallow metadata of projected columns, including comments and default expressions, which isn't ideal. This could be fixed by modifying generateProjection method in TransformParser.
