支持flashback功能

./mysqlbinlog -B |mysql

pasrebinlog_stat.py

1. 安装需要的 Python 模块

pip install xlwt
pip install pandas

2. 创建使用 pasrebinlog 解析后生成文件的存放位置

注意: 每一个binlog生成一个统计文件

mkdir -p /tmp/binlog_parse

3. pasrebinlog 使用 pasrebinlog 生成统计文件保存到 /tmp/binlog_parse 目录中

ll /u01/other/backup/app_db/binlog/mysql-bin.00193* | \
    awk -F ' |/' '{print "/home/manager/script/mysql-binlog-statistic/bin/pasrebinlog /u01/other/backup/app_db/binlog/" $NF " > /tmp/binlog_parse/" $NF ".log"}' | \
    /bin/bash

4. 使用 pasrebinlog_stat.py 生成相关

python pasrebinlog_stat.py /tmp/binlog_parse > format.txt

5.查看生成的文件
