----------------------------------

             Summary: the column lost comments, also find some issue ,but that commit is not mr. i have some diff  solution
                 Key: FLINK-30325
                 URL: https://issues.apache.org/jira/browse/FLINK-30325
             Project: Flink
          Issue Type: Improvement
          Components: Connectors / Hive, Table SQL / Planner
    Affects Versions: 1.16.0, 1.14.3
         Environment: flink: 1.14.3
            Reporter: blackpighe
             Fix For: 1.14.3


In the process of using flink in the company, column level comment were found to be lost, and there was also an issue in the community discussing these issues, but they try to modify the structure of the table schema to fix it. I have a better solution here. The basic idea is to upgrade TableSchema to ResolvedSchema. However, there are some problems if an external component uses a lower version of flink and may not have a ResolvedSchema.
