An application that tracks orders, accounts or other structured records needs a database that can store related data and update it consistently. MariaDB is a relational database: it organizes records into tables and uses SQL to query and change them. It grew from MySQL and shares parts of its client ecosystem, making it familiar to many teams. That shared history does not make current versions interchangeable without checking application and migration requirements.
Current guidance
The historical description overgeneralizes MySQL replacement. MariaDB’s own compatibility documentation qualifies the original drop-in behavior by version and catalogs growing differences in later releases. Shared client protocols do not imply interchangeable data files, SQL behavior, replication identifiers or storage-engine plugins.
Before moving an application, identify the exact source and destination versions, engines, collations, JSON usage, stored routines and authentication methods. Use the relevant compatibility pages rather than applying old MySQL 5.x advice to a modern database. Treat the server image, Kubernetes chart and any replication operator as separate versioned components.
Rehearse a supported export/import or upgrade path with representative data and verify application queries, constraints, accounts and restore time. Preserve a recoverable source before writes are accepted on the destination; simply switching back after divergent writes is not a rollback plan. Review backups independently of replica health. This guidance corrects the historical compatibility claim without declaring either application retired or certifying an untested cross-engine migration.

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.
