pymysqlbinlog 是分析/解析binlog的开源工具, 使用GPL-3.0 license
项目地址: https://github.com/ddcw/pymysqlbinlog
为了方便展示, 我这里尽量使用sql格式, 但是默认的元数据minimal格式不记录字段名字, 所以就先设置为full. 数据解析的时候建议使用 base64格式
set global binlog_row_metadata = full;建议使用源码, 我也懒得去编译了 -_-
如果是基于表/库级匹配, 则会破坏事务的完整性. 基于gtid/时间等则不会破坏事务完整性.

DELIMITER ;python main.py /data/mysql_3314/mysqllog/binlog/m3314.000037 --sql --rollback我们可以看到刚才的那个delete 已经变为了insert
其实讲row_event的时候就验证过了的...
mysql -h127.0.0.1 -P3314 -p123456 -e 'checksum table db1.sbtest1;'
mysql -h127.0.0.1 -P3314 -p123456 -e "delete from db1.sbtest1 limit 10;"
python main.py /data/mysql_3314/mysqllog/binlog/m3314.000039 --rollback | mysql -h127.0.0.1 -P3314 -p123456
mysql -h127.0.0.1 -P3314 -p123456 -e 'checksum table db1.sbtest1;'
注意: 会列出所有的trx信息, 所以可能会很大.... (后面我再调一下这玩意....)
python main.py /data/mysql_3314/mysqllog/binlog/m3314.000039 --analyze -o /tmp/t20240504_10.md
这个工具差不多写了快一个月了, 写得断断续续的....
后面应该会出一个视频来详细介绍的. 毕竟我也经常用.
