server

MariaDB Server is one of the most widely deployed open-source relational databases, built by a global community of contributors together with the MariaDB Foundation and MariaDB plc. It began as a fork of MySQL, led by the original MySQL developers, and maintains a high degree of MySQL compatibility while adding its own capabilities. Key features include: * **Native vector search**: A built-in VECTOR data type with approximate nearest-neighbour indexing (HNSW), available since MariaDB 11.8 with no extension required. * **Pluggable storage engines**: InnoDB (default for transactional workloads), Aria, MyRocks, ColumnStore for analytics, Spider for sharding, and S3 for archival, among others. * **Replication and clustering**: Asynchronous, semi-synchronous, and parallel replication with global transaction IDs, plus Galera synchronous multi-primary clustering. * **Advanced SQL**: Common table expressions and recursive CTEs, window functions, system-versioned (temporal) tables, sequences, and a broad set of JSON functions. * **MySQL and Oracle compatibility**: Wire-protocol and syntax compatibility with MySQL, plus an Oracle SQL mode supporting PL/SQL-style stored routines. * **Spatial and full-text search**: GIS data types and functions, and built-in full-text indexing. * **Security**: Role-based access control, pluggable authentication (ed25519, PAM, GSSAPI, and more), data-at-rest encryption, and TLS for connections. MariaDB Server follows a yearly long-term support (LTS) model alongside quarterly rolling releases. Binary LTS releases are maintained for three years and are recommended for production; rolling releases deliver new features sooner with a shorter support window. Packages and installation instructions for all supported platforms are available at the MariaDB download page. Building from source and running the test suite is covered in the developer guide. Contributions are welcome, from code and documentation to bug reports and reviews. MariaDB Server is licensed under version 2 of the GNU General Public License (GPLv2), without the "any later version" clause, inherited from MySQL. The MariaDB Foundation is the custodian of the codebase, ensuring it stays open and that anyone can contribute.
