> The reason is that org.apache.flink.table.api.TableSchema#toPhysicalRowDataType lost column comments, which leads to comparison failure in AbstractTableStoreFactory#buildFileStoreTable.

> The reason why Flink does not encounter this problem is due to the column is lost before persisting the schema
