MariaDB is a community-developed fork of the MySQL relational database management system, the impetus being the community maintenance of its free status under the GNU GPL. Being a fork of a leading open source software system, it is notable for being led by its original developers and triggered by concerns over direction by an acquiring commercial company Oracle. Contributors are required to share their copyright with Monty Program AB.
The intent is also to maintain high compatibility with MySQL, ensuring a "drop-in" replacement capability with library binary equivalency and exact matching with MySQL APIs and commands. It includes the XtraDB storage engine for replacing InnoDB, as well as a new storage engine, Aria, that intends to be both a transactional and non-transactional engine perhaps even included in future versions of MySQL.
Its lead developer is Michael "Monty" Widenius, the founder of MySQL and Monty Program AB. He had previously sold his company, MySQL AB, to Sun Microsystems for US$1 billion. MariaDB is named after Monty's younger daughter, Maria.
MariaDB version numbers, until 5.5, followed MySQL's numbers. Thus, if one uses MariaDB 5.5 one knows that all features from MySQL 5.5 are available.
Notably, there exists a gap in MySQL versions between 5.1 and 5.5 while MariaDB issued point releases for 5.2 and 5.3.
After 5.5, MariaDB developers decided to start a branch numbered 10. This change has been made to make it clear that MariaDB will not import all features from MySQL 5.6 in 10.0 (they may or may not be ported in future versions). In some cases the reason is that some of those features seem not to be stable enough for MariaDB standards. Since new specific features have been developed in MariaDB, the developers decided that a major version number was necessary.
MariaDB's API and protocol are compatible with those used by MySQL, plus some features to support native non-blocking operations and progress reporting. This means that all connectors, libraries and applications which work with MySQL should also work on MariaDB—whether or not they support its native features. On this basis, Fedora developers replaced MySQL with MariaDB in Fedora 19, out of fears that Oracle is making MySQL a more closed software project.
Here is a list of tools that are known to work properly with MariaDB:
- DBEdit — a free administration application for MariaDB and other databases.
- SQLyog — a database management application on Windows, Linux.
- Navicat — a series of proprietary database management applications for Windows, Mac OS X, and Linux.
- HeidiSQL — a free and open source client for MySQL on Windows. It supports MariaDB specific features like Virtual Columns, and is included with the Windows MSI package of MariaDB beginning with the 5.2.7 release.
- phpMyAdmin — a web-based database management application for MySQL
The following applications officially support MariaDB:
In December 2012, Michael Widenius, David Axmark, and Allan Larsson announced the creation of a foundation that would oversee the development of MariaDB. In April 2013, the Foundation announced that it had appointed Simon Phipps as its Secretary and interim Chief Executive Officer, Rasmus Johansson to Chair of the Board, and Andrew Katz, Jeremy Zawodny, and Michael Widenius to Board members. Noting that it wished to create a governance model similar to that used by the Eclipse Foundation, the Board appointed the Eclipse Foundation's Executive Director Mike Milinkovich as an advisor to lead the transition.
SkySQL, a company formed by ex-MySQL executives and investors after Oracle bought MySQL, announced in April 2013 that they were merging their company with Monty Program Ab, and joining the MariaDB Foundation. SkySQL's CEO Patrik Sallner would lead the new merged company, and Widenius was appointed as its CTO by the MariaDB Foundation.
