This short blog post is an announcement regarding the Matomo (Piwik) technology stack.
Matomo compatible with MySQL and MariaDB
Since our first public release Matomo (Piwik) uses the open source database server MySQL to store the analytics data.
Matomo (Piwik) is also compatible with MariaDB. MariaDB is an enhanced, drop-in replacement for MySQL.
Upgrading to MariaDB
Many users from our community as well as Matomo (Piwik) Scalability Experts have confirmed that using MariaDB for Matomo has several advantages. MariaDB has in some cases significantly improved query performance and reliability of Matomo. Because MariaDB 5.5 is a complete drop-in-replacement for MySQL 5.5, upgrading can be as easy as running
apt-get install mariadb-server (or equivalent for your platform). Existing third party techologies such as TokuDB (FAQ) and Galera are fully compatible with MariaDB.
