Description
For example, UPDATE statement. It currently writes Update_rows_event and Write_row_event for every updated row. It should write only Update_rows_event, and the slave, when executing it, should create the historical row internally. Because existing binlogs already have Update_rows_event and Write_row_event, the slave should ignore all events that modify the history.
