MySQL 使用infobin查找binlog中大事务

某些时候需要判断binlog中是否有大事物的存在，比如在解决master-slave延迟高的情况下。

表结构

< yoon]> show create table a\G
*************************** 1. row ***************************
       Table: a
Create Table: CREATE TABLE `a` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `order_id` bigint(20) DEFAULT NULL,
  `name` varchar(49) DEFAULT NULL,
  `sexy` varchar(20) DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `idx_order_id_name` (`name`,`order_id`)
) ENGINE=InnoDB AUTO_INCREMENT=19 DEFAULT CHARSET=utf8mb4

创建一个事务

< yoon]> show variables like 'autocommit';

< yoon]> set autocommit = 0;

< yoon]> insert into a (order_id,name,sexy) values (6,'CCC','N');

< yoon]> insert into a (order_id,name,sexy) values (6,'CCC','N');

< yoon]> insert into a (order_id,name,sexy) values (6,'CCC','N');

< yoon]> set autocommit = 1;

infobin

[root@127-0-0-1 u01]# ./infobin
[binlogfile]:binlog file!
[piece]:how many piece will split,is a Highly balanced histogram,
        find which time generate biggest binlog.(must:piece<2000000)
[bigtrxsize](bytes):larger than this size trx will view.(must:trx>256(bytes))
[bigtrxtime](sec):larger than this sec trx will view.(must:>0(sec))
[[-t]]:if [-t] no detail is print out,the result will small
[[-force]]:force analyze if unkown error check!!

【piece】：分片参数，比如1G的binlog分为10片那么1片就是100M左右
【bigtrxsize】：
【bigtrxtime】：时间，单位秒

使用infobin来查看binlog日志，10代表分10片，2000000代表2MB，1大表1秒

[root@127-0-0-1 u01]# ./infobin mysql-bin.000012 10 2000000 1 -t > hank.log

查看hank.log日志

[root@127-0-0-1 u01]# cat hank.log
