Advantages of row-based replication 1所有的更改都可以被复制,是一种安全的复制2对于主库而言只有少量的行锁,从而实现较高的并发性2.1insert ...select2.2带有auto_increment的insert语句2.3对于update或delete语句,使用where字句不使用键或者不会更改大多数已经检查的行2.4在从库中任意使用insert ,update或delete语句只...
Binlog格式为ROW mysql binlog row statement binlog有三种格式:Statement、Row以及Mixed。 –基于SQL语句的复制(statement-based replication,SBR), –基于行的复制(row-based replication,RBR), –混合模式复制(mixed-based replication,MBR)。 1、Statement 记录每一条修改数据的SQL语句(批量修改时,记录的不是单条...
binlog的格式也有三种:STATEMENT、ROW、MIXED 。 1、STATMENT模式:基于SQL语句的复制(statement-based replication, SBR),每一条会修改数据的sql语句会记录到binlog中。 优点:不需要记录每一条SQL语句与每行的数据变化,这样子binlog的日志也会比较少,减少了磁盘IO,提高性能。 缺点:在某些情况下会导致master-slave中...
解释 这是因为,mysql默认的binlog_format是STATEMENT。 从MySQL 5.1.12 开始,可以用以下三种模式来实现:基于SQL语句的复制(statement-based replication, SBR),基于行的复制(row-based replication, RBR),混合模式复制(mixed-based replication, MBR)。相应地,binlog的格式也有三种:STATEMENT,ROW,MIXED。 如果你采用...

For more information, seeSection 16.4.1.15, “Replication and System Functions”. Statements that cannot be replicated correctly using statement-based replication are logged with a warning like the one shown here: [Warning] Statement is not safe to log in statement format. ...
http://dev.mysql.com/doc/refman/5.1/en/replication-sbr-rbr.html Statement based will replicate the statement regardless of any errors I believe. From the manual here: http://dev.mysql.com/doc/refman/5.0/en/binary-log.html The binary log contains “events” that describe database changes su...
* when using STATEMENT mode, a warning that the statement is not safe for statement-based replication is now issued ... [end] In other words: To make statements using LIMIT safe for SBR, you need an ORDER BY as well. I am adding a statement to this effect to the page in question....
