MariaDB is an open source relational database management system (DBMS) that is a compatible drop-in replacement for the widely used MySQL database technology. It was created as a software fork of MySQL by developers who played key roles in building the original database; they devised MariaDB in 2009 in response to Oracle Corp.’s acquisition of MySQL.
MariaDB is based on SQL and supports ACID-style data processing with guaranteed atomicity, consistency, isolation and durability for transactions. Among other features, the database also supports JSON APIs, parallel data replication and multiple storage engines, including InnoDB, MyRocks, Spider, Aria, TokuDB, Cassandra and MariaDB ColumnStore.
Much of the development work on the open source database has focused on achieving feature parity between MariaDB and MySQL. MariaDB Corp., the driving force behind MariaDB, says that “for all practical purposes” the database is binary-compatible with MySQL. As a result, most users can switch between the two technologies simply by uninstalling MySQL and installing MariaDB in its place.
Nonetheless, there are some incompatibilities between corresponding versions of the databases. For example, in version 10.1 and above, MariaDB stores JSON data in a different format than MySQL 5.7 does. To compensate, users looking to replicate columns of JSON objects from MySQL to MariaDB need to either convert them to the format used by the latter or run statement-based replication jobs via SQL.
MariaDB Corp., based in Espoo, Finland, with U.S. headquarters in Menlo Park, Calif., offers a commercial version of MariaDB on a subscription basis, along with complementary products and a set of training, remote management, and migration services. However, the database’s source code is maintained by the MariaDB Foundation, a group that was formed in 2012 to preserve the software’s open source nature.
