For years, MySQL has been fundamental to many server applications, especially those using the LAMP (Linux, Apache, MySQL, Perl/PHP/Python) software stack. Those days may be ending. Both Fedora, Red Hat's community Linux, and openSUSE, SUSE's community Linux, will be switching out MySQL to MariaDB for their default database management system (DBMS) in their next releases.
Fedora & openSUSE will both be switching out MySQL for MariaDB in their next Linux releases.
For database developers and managers this change shouldn't be a problem. MariaDB, a MySQL fork founded by the original MySQL developers, is designed to be a drop-in replacement for the MySQL Database Server. It includes support for all the major open source storage engines, which are also supported by MySQL, such as MyISAM, Blackhole, CSV, Memory, and Archive.
Michal Hrušecký, an openSUSE developer and the MySQL maintainer for openSUSE and SUSE, explained, With MariaDB you'll still be using the "same API [application programming interface], still same protocol, even same utilities. And mostly the same datafiles. So unless you have some deep optimizations depending on your current version, you should see no difference."
