Semi-sync only guarantees that the slave has *received* the statement in it's relay log. The rpl_semi_sync_master_timeout value is the timeout for the slave to acknowledge this, whereas the Seconds_Behind_Master value gives an indication of how far statement *execution* is lagging. -- Unhappiness is discouraged and will be corrected with kitten pictures. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql
