What is MariaDB?

MariaDB is an in­de­pend­ent re­la­tion­al database man­age­ment system that offers high per­form­ance, flexible storage engines, and seamless com­pat­ib­il­ity with MySQL. It also stands out due to its com­pre­hens­ive security features, JSON support, and easy scalab­il­ity. Some typical use cases for MariaDB databases include web ap­plic­a­tions, cloud databases, e-commerce, and en­ter­prise ap­plic­a­tions.

What is MariaDB?

MariaDB is a general-purpose open-source re­la­tion­al database man­age­ment system that was released in 2009 as a fork of MySQL. It is among the most popular database servers worldwide and is used by Google, WordPress, and Wikipedia, among others. The MariaDB Found­a­tion co­ordin­ates the ongoing de­vel­op­ment of the platform, over­see­ing release cycles, quality assurance and security updates. MariaDB is published under the GPLv2 licence, meaning it is an open source database man­age­ment system or DBMS, for short.

Like MySQL, MariaDB uses the re­la­tion­al database model, or­gan­ising data into tables. These tables can be related to each other, enabling complex queries and efficient data man­age­ment. MariaDB databases are based on the universal language SQL (Struc­tured Query Language), which is designed for accessing and managing data in re­la­tion­al databases. For example, the SQL command SELECT is used to query data, while the command INSERT allows data to be inserted into a table.

MariaDB is pro­grammed in C and C++, but it also supports other pro­gram­ming languages such as Java, Python, PHP, and Perl. It is also designed for all major operating systems – Windows, Linux, and macOS – making it cross-platform com­pat­ible.

What features does MariaDB offer?

MariaDB has an extensive set of features that meet modern demands for per­form­ance, scalab­il­ity, and security. Here is a non-ex­haust­ive list of its functions:

• Modular storage engines: MariaDB databases provide multiple storage engines designed for different needs. InnoDB is designed for general trans­ac­tion storage. Aria allows for easy copying of tables between different systems and MyRocks offers stronger com­pres­sion. OQGRAPH handles hier­arch­ies and complex graphs.
• ACID com­pli­ance: MariaDB supports trans­ac­tions with ACID prop­er­ties (Atomicity, Con­sist­ency, Isolation, Dur­ab­il­ity). This ensures that all op­er­a­tions within a trans­ac­tion are either fully completed or not at all, and are rolled back in case of errors, ensuring data integrity even during system failures.
• Rep­lic­a­tion and scaling: The platform is capable of dis­trib­ut­ing loads across multiple servers. Column­Store is spe­cific­ally developed for big data scaling. Ad­di­tion­ally, Galera offers a syn­chron­ous multi-master cluster. Spider uses par­ti­tion­ing to achieve data sharding across servers.
• Advanced SQL functions: Features like Window Functions, Common Table Ex­pres­sions (CTEs), and JSON data types enable the creation of complex queries and modern data models.
• Extensive security features: MariaDB not only provides regular security updates, en­cryp­tion, and role-based access control but also numerous plugins for au­then­tic­a­tion.

What ad­vant­ages does MariaDB offer?

MariaDB combines per­form­ance, open-source ac­cess­ib­il­ity and flex­ib­il­ity, making it suitable for projects of any size: Whether it’s small web ap­plic­a­tions or mission-critical systems, users of MariaDB enjoy numerous benefits. The following overview sum­mar­ises the key ad­vant­ages:

• Com­pletely open-source and free: MariaDB is under the GPLv2 licence. This elim­in­ates licensing fees and gives you full access to the source code, offering great freedom to customise and expand the software.
• Com­pat­ib­il­ity with MySQL: MariaDB is com­pat­ible with MySQL. This means existing ap­plic­a­tions, tools, and scripts using MySQL can usually be switched over with minimal effort.
• High per­form­ance: With features like spe­cial­ised storage engines, MariaDB can quickly process requests even under heavy load and with large data volumes. Ho­ri­zont­al scaling through rep­lic­a­tion and clus­ter­ing can be easily con­figured.
• Active community: A global community of de­velopers and companies con­trib­utes to the ongoing de­vel­op­ment of MariaDB databases. These receive regular updates and new features.

What is MariaDB most suitable for?

MariaDB is suitable for a wide range of ap­plic­a­tions, from classic web projects to data-intensive en­ter­prise solutions and modern cloud and Big Data en­vir­on­ments. It is also ideal for everything from simple entry-level projects to complex software ar­chi­tec­tures. Classic use cases include:

• Web ap­plic­a­tions: MariaDB is often used to manage data in web ap­plic­a­tions. An example includes content man­age­ment systems like WordPress, Joomla!, or Drupal, which operate reliably on MariaDB despite high traffic volumes.
• Cloud databases: Many cloud providers like Amazon Web Services (AWS), Google Cloud, and Microsoft Azure offer MariaDB as a fully managed service. This allows MariaDB databases to be scaled flexibly and main­tained auto­mat­ic­ally.
• Online stores: In e-commerce systems like Magento, MariaDB manages product cata­logues, orders, and customer data. Even with a high number of users, MariaDB databases ensure fast trans­ac­tions.
• Mission-critical ap­plic­a­tions: MariaDB is also used in en­ter­prise en­vir­on­ments that require high avail­ab­il­ity and per­form­ance.

What are some re­com­men­ded al­tern­at­ives to MariaDB?

The most obvious MariaDB al­tern­at­ive is MySQL, which is one of the world’s most popular re­la­tion­al database man­age­ment systems. MySQL is known for being very easy to use and for having strong support from Oracle, which helps users quickly resolve issues. It also offers broad com­pat­ib­il­ity with various pro­gram­ming languages, platforms, and systems – a trait it shares with MariaDB. In fact, some Linux dis­tri­bu­tions, such as Fedora, CentOS, and Arch Linux, have even adopted MariaDB as their default database system in place of MySQL.

Several other solutions are worth con­sid­er­ing as al­tern­at­ives. MongoDB is par­tic­u­larly well-suited for handling large volumes of data, offering virtually unlimited ho­ri­zont­al scalab­il­ity. Apache Cassandra also excels in big data en­vir­on­ments thanks to its robust scaling cap­ab­il­it­ies. Meanwhile, Google’s Firebase is spe­cific­ally optimised for mobile apps.
