blackpighe commented on FLINK-30325:
------------------------------------
Yes, I only want to be responsible for 1.14.3 now, because our company used
1.14.3. At that time, the version of tableschema had been marked for deletion
and partially used the new ResolvedSchema. The lack of column comment made our
product experience poor. Does the flink community have any ideas about fixing
the bug in the lower version, even though this change is specific to 1.14.3 and
may not be incorporated into the latest version? I can provide solutions and
code
> the column lost comments, also find some issue ,but that commit is not mr. i
> have some diff solution

> 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.
