About MariaDB Server

MariaDB Server is one of the most popular database servers in the world. It’s made by the original developers of MySQL and guaranteed to stay open source. Notable users include Wikipedia, WordPress.com and Google.

MariaDB Server turns data into structured information in a wide array of applications, ranging from banking to websites. Originally designed as enhanced, drop-in replacement for MySQL, MariaDB Server is used because it is fast, scalable and robust, with a rich ecosystem of storage engines, plugins and many other tools make it very versatile for a wide variety of use cases.

MariaDB Server is developed as open source software and as a relational database it provides an SQL interface for accessing data. The latest versions of MariaDB Server also include GIS and JSON features.

More information can be found in the MariaDB Server Knowledge Base, for example:

MariaDB Server Success Stories

There is also a good Wikipedia article about MariaDB Server and the MySQL history.

MariaDB Server will remain Free and Open Source Software licensed under GPLv2, independent of any commercial entities.

MariaDB Server in brief

About MariaDB Foundation

The cornerstones of the MariaDB Foundation mission are Openness, Adoption, and Continuity.

  • We ensure the MariaDB Server code base remains open for usage and contributions on technical merits.
  • We strive to increase adoption by users and across use cases, platforms and means of deployment.
  • We provide continuity to the MariaDB Server ecosystem, independent of any commercial entities.

The MariaDB Foundation is the global contact point for collaboration on MariaDB Server.

The Foundation is non-profit incorporated in Delaware, USA. and is funded by corporate and individual sponsors.

The Foundation’s staff supports MariaDB Server by:

  • Encouraging adoption, contribution and distribution of MariaDB Server and related open source software.
  • Helping new contributors understand the source code and lowering the barrier for new participants.
  • Participating in the design of new features, ensuring the code quality and maintainability of the codebase while the number of contributors is growing.
  • Making sure documentation keeps up with the development of new features.
  • Porting and packaging MariaDB Server to different platforms and operating systems to keep it as widely available as possible.
  • Speaking at events and driving adoption.

Details about the Foundation’s principles, operation and the board of directors are available on the Governance page. More information regarding board meeting minutes can be found here.

While the Foundation’s staff do work on the code base and develop MariaDB Server to some extent, the mission of the Foundation is not to develop MariaDB Server as much as possible, but to empower a large as possible community to be successful in collaborative MariaDB Server development.

At Sun, Kaj served as MySQL Ambassador to Sun and Sun VP of Database Community. Board member at Footbalance Systems Oy (Helsinki, Finland). Past founder, CEO and 14 year main entrepreneur of Polycon Ab (Finland).

Kaj is a co-founder of MariaDB Corporation Ab, and served on its Executive Team in several positions, most recently Chief Evangelist.

Kaj lives and works in Munich, Germany, and during summer often in Nagu, Finland. He is a citizen of both countries. Kaj holds a M.Sc. (Eng.) from Helsinki University of Technology (now Aalto University) and an MBA from Hanken School of Economics.

Programming-wise, Kaj started out on the TI-58 in the 1970s, followed by Basic and a bit of assembler on the ABC-80 and ABC-800, together with Michael “Monty” Widenius. Kaj took fondness to APL on mainframes, before settling on the 4GL Focus as the technical basis for his first company Polycon. After a Visual Basic period, a Delphi period and a brief PHP period, Kaj moved out of programming into management, only to realise in 2011 that Python is good for his mental well-being. His venture into geodata with Python even left some superficial traces on Github.

Licensing-wise, Kaj contributed to GPLv3 as co-chair of the industry Committee B, advising the FSF on GPLv3 in 2006-07, observing how Eben Moglen led the process towards industry consensus.

These dates constitute the public policy of the MariaDB Foundation and are not legally binding. The software is released with the GPL license as-is, without warranties.

Exceptions for MariaDB versions in widespread use

The MariaDB Foundation may decide to maintain selected releases beyond the normal 5 years if they are in exceptionally widespread use. As MariaDB 5.5 was included in multiple prominent Linux distributions with a lifespan beyond 2017, the Foundation committed to maintaining it until 2020.

Maintenance periods by service providers

Some MariaDB service providers might offer under contract longer, or otherwise more extensive, maintenance periods. Some Linux distributions may also offer extended support periods for the MariaDB versions they shipped.

Please contact the commercial service providers if you use MariaDB in a critical production environment and you want to have contractual warranties regarding your use and maintenance of the MariaDB software.

Semantic versioning

MariaDB aims to follow the semantic versioning standard. In client-server APIs we follow it fully and in the server we follow it in spirit.

Micro releases (patch versions) e.g. 5.5.x and 10.0.x only fix security issues and bugs. Minor version releases e.g. 5.x and 10.x add functionality but maintain backwards-compatibility. Major releases e.g. 10.0 and 11.0 may make backwards-incompatible changes.

For details about semantic versioning, see semver.org.

In all releases, including major releases, we always make sure that the mysql_upgrade facility runs correctly and the database files from any older release can be upgraded.

Privacy policy

MariaDB Foundation strongly believes in privacy laws and adheres to the rules of GDPR. View our full privacy policy here.

Security policy

MariaDB Foundation is committed to ensuring all security bugs are fixed within stable MariaDB Server versions. Security issues can be reported via security@mariadb.org or under the HackerOne Program.

The MariaDB Server developers classify all security bugs according to their threat level. The threat level can be one of:

  • Critical: an exploitable vulnerability that causes arbitrary code execution or allows an unauthenticated user to crash the server or get access to the data.
  • Medium: everything else.

We strive to fix any Critical security bug immediately, usually within hours, and release fixed MariaDB binaries as soon as possible, usually the next day.

We will fix Medium security bugs as soon as possible, but we will not change our planned release schedule to get the fix out earlier.

Please review our Security Policy and Assets covered within that we have available on our HackerOne profile.

We will also follow responsible disclosure procedures and also alert related projects and forks such as Oracle MySQL and Percona Server if we believe a reported security issue affects those projects as well.

We are flexible about the usage of the logo when addressing MariaDB Foundation. We recommend keeping the colours the same unless changing the scheme fits better with the final artwork.

Usage statistics

Beginning in October 2011, MariaDB Server included a new User Feedback plugin. When the plugin is activated (it is inactive by default), it can periodically upload configuration and usage information to mariadb.org. Alternatively, one can upload this information manually using the Upload Data page or with popular command line tools.

The information gathered by the User Feedback plugin provides the MariaDB project with useful input in form of:

  • which platforms and hardware MariaDB is run on
  • an indication of the worldwide distribution of MariaDB
  • the version and build numbers of MariaDB that are in use
  • features that are used

The main purpose behind collecting this kind of information is to use it to steer engineering and community development of MariaDB Server in the right directions. The information is used to continuously improve the product.

The User Feedback plugin gathers only non-sensitive information such as:

  • processor type, speed, amount of processors/cores
  • operating system, distribution, and kernel information
  • storage engines that are in use
  • list of loaded plugins
  • and other similar data

The User Feedback plugin will never send any personal or sensitive information such as user names, database names or contents, or anything that would enable the tracking of the user.

The complete manual of the User Feedback plugin, including instructions for how to see what exactly is being sent, can be found on the User Feedback plugin page of the MariaDB Knowledgebase.
