setglobal sync_master_info=10000; 然后,在主库插入一条记录。再到从库去查看 selectfrom mysql.slave_master_info \G 结果中的Master_log_pos字段值。并执行show slave status \G 查看Exec_Master_Log_Pos值。可以重复操作几次数据插入,可以发现show slave status \G 和mysql.slave_master_info里面对不上了。
master_info_repository有两个值,分别是file和table,该参数决定了slave记录master的状态,如果参数是file,就会创建master.info文件,如果参数值是table,就在mysql中创建slave_master_info的表。 sync_master_info参数决定slave刷新master的状态的方式。并且master_info_repository的参数不同,刷新方式也不同。 1)如果master_...
如果设置master_info_repository=TABLE,那么sync_master_info的值>0,slave 更新它的master info 每sync_master_info events 如果设置为0,表永远不给更新。 master_info_repository=FILE. If the value of sync_master_infoisgreater than0,the slave synchronizes its master.infofile to disk(using fdatasync())a...

2.set sync_master_info =0. 3.Enable log_warnings=4. 4.start slave to notice slave IO is sending the binlogs from master to slave relay log. slave received the data to relaylogs in full.(1.1G similar to master) 5. now, set sync_master_info=1 and start noticing the relay log ...
(treated as a fake rotate event) to signal the end of a skip period. Sounds great, until you get to the slave handling code, which takes that event and forces a master info sync on every heartbeat - even these dummy ones. This can, even in a somewhat simple setup, lead to a ~5X...

show slave status \G 展示的是基本实时的exec_master_log_pos数据。但是 selectfrom mysql.slave_master_info \G 里面却迟迟不更新。 这就是sync_master_info参数的功效。 说明: 如果set global sync_master_info=1的话,理论上复制会更安全,但是这样的话执行每个event都要去update一次 mysql.slave_master_info...
