Maatkit is a toolkit for users, developers, and administrators of open-source databases. It is high-quality, formally tested software that is well documented and has an active open-source developer community. It has some unusual goals: all tools are standalone, with minimal dependencies and no need for installation. You can simply download them and use them. Documentation is embedded in the tools themselves. There are many more nice attributes, too.
Most of Maatkit’s functionality is designed for MySQL. It makes MySQL easier and safer to manage. It provides simple, predictable ways to do things you cannot otherwise do. That’s why Maatkit is now shipping by default with many GNU/Linux distributions such as Debian and CentOS. You can use Maatkit to prove replication is working correctly, fix corrupted data, automate repetitive tasks, speed up your servers, and much more.
In addition to MySQL, there is support for PostgreSQL, Memcached, and a growing variety of other databases and technologies.
Maatkit is generously sponsored by many organizations and individuals who rely on its functionality every day.
