## What it is
MyFlash is a command-line tool developed by Meituan-Dianping that parses MySQL v4 binlogs to generate SQL for rolling back DML operations (insert, update, delete) to any point in time. It offers richer filtering options than existing rollback tools and is used in production at Meituan.

## Use cases
- undo a bad update or delete on a mysql table
- flashback mysql data to a previous point in time
- roll back accidental dml changes using binlog
- recover deleted rows in mysql without restoring a backup
- generate reverse sql from mysql binlog

## When to choose
- you need to reverse specific DML operations on MySQL 5.6/5.7 with row-format binlog
- you want fine-grained filtering of which statements to roll back
- you need a fast, production-proven flashback tool

## When to avoid
- your MySQL uses statement-based binlog or binlog_row_image is not full
- you run MySQL 8.0 or newer
- you need to roll back DDL operations
