> Currently in FlinkCDC 3.3, we've support sync the comments of table and columns at the first acquisition. However, after the user modifies the comments in the source table, we cannot continue synchronizing this information.
> Adding AltertableCommentEvent and AlterColumnCommentEvent will us keep the comments of upstream and downstream tables as consistent as possible.
