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. Documentation is embedded in the tools themselves. There are many other 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. 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.
