[jira] [Created] (FLINK-20029) Define the computed column on the metadata column

Shengkai Fang created FLINK-20029:
-------------------------------------

             Summary: Define the computed column on the metadata column
                 Key: FLINK-20029
                 URL: https://issues.apache.org/jira/browse/FLINK-20029
             Project: Flink
          Issue Type: Bug
          Components: Connectors / Kafka, Table SQL / API
    Affects Versions: 1.12.0
            Reporter: Shengkai Fang
             Fix For: 1.12.0


Currenlty it's not allowed to define the computed column on metadata. It's very useful when users extract the metadata from record and use the information as watermark.
