The current data structure has changed and the data before parsing binlog will go wrong

For example: the current time is 6 points, and now the binlog parsing time is 5 points, at 6 points to the table structure added a field, at this time binlog parsing will have problems

The issue names no files, tests, or entry points. Reproduce the described case by changing a table schema after a binlog event is written, then determine the expected behavior for parsing the earlier binlog and verify that the parser handles the schema change without errors.
