My immediate impression is that this sounds like a bad idea. It increases the binlog size without adding any real information - after all the event count can be determined easily by just reading the events. It also requires careful design and testing for impact on forwards- and backwards compatibility. And event count is not a very meaningful progress indicator. One event group could have 10 Rows_log_event each with a single row operation. While another could have a single Rows_log_event that contains a hundred row operations. And why only rows event? What about Query_log_events in a transaction in statement-based replication? - Kristian. _______________________________________________ Mailing list: https://launchpad.net/~maria-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~maria-developers More help : https://help.launchpad.net/ListHelp
