## What it is
MyDumper is a high-performance, multithreaded logical backup tool for MySQL, MariaDB, Percona, and TiDB databases. It consists of mydumper for exporting consistent backups and myloader for importing them in parallel.

## Use cases
- dump a mysql database quickly with parallel threads
- create a consistent backup of a mariadb database
- restore a mysql dump into another server with myloader
- back up a database while capturing replication master/slave positions
- export only selected tables or schemas using regex filters
- migrate a database between mysql instances

## When to choose
- you need fast, parallel logical backups of MySQL-compatible databases
- you require consistent snapshots with accurate binlog positions for replication
- you want per-table output files that are easy to parse and restore selectively

## When to avoid
- you need physical or hot backups of non-transactional engines
- you use a database other than MySQL/MariaDB/Percona/TiDB
- you prefer a managed backup solution with built-in scheduling and retention
