Michael “Monty” Widenius, MySQL’s original author, forked MySQL in 2009 amid concerns about Oracle’s pending purchase of Sun. MariaDB is named after his younger daughter, Maria. It aimed to stay a drop-in replacement for MySQL, and from 2013 several major Linux distributions, including Fedora, openSUSE and later RHEL 7, made it their default.
The two databases have drifted apart since then. MariaDB jumped to version 10 in 2014 and added features such as system-versioned tables, sequences and many storage engines. The non-profit MariaDB Foundation looks after the code, and the company MariaDB plc sells enterprise support. Rolling releases arrive every quarter, and one release a year becomes a long-term release with five years of support.
