MariaDB and MySQL are both popular open-source relational database management systems that originated from the same code base but have since evolved in different directions. Although they share many similarities and are mostly compatible with each other, there are distinct differences between them that may influence which one is best suited for your needs.
Below is a comparison between MariaDB and MySQL, highlighting their key features and differences:
- Licensing and Open Source Commitment:
MariaDB is completely open-source under the General Public License (GPL), ensuring ongoing community development and contributions. MySQL, while available under GPL for its community edition, offers a paid proprietary enterprise edition that includes additional features such as enhanced security, backup tools, and support for high-performance replication. There are ongoing concerns further development and features will be focused be on the Paid enterprise version.
-
Performance and Scalability:
MariaDB generally offers better performance in certain scenarios, especially in replication and query speed, thanks to its enhancements and optimizations. For instance, MariaDB's thread pooling is available in its community version and supports handling a higher number of connections, making it a strong choice for high-demand applications. MySQL also provides thread pooling, but only in its enterprise edition.
-
Storage Engines:
MariaDB supports a wider variety of storage engines than MySQL, such as Aria, XtraDB, and Cassandra, giving users more options for optimizing databases based on their specific use cases. MySQL, on the other hand, focuses primarily on the InnoDB engine.
-
Enterprise Support and Stability:
MySQL’s enterprise edition, backed by Oracle, includes features tailored for large-scale, mission-critical applications. These features include enhanced security (e.g., MySQL Enterprise Firewall and transparent data encryption), as well as enterprise-grade support and automated failover options.
MySQL’s slower rate of introducing new features also ensures greater stability, which can be crucial for businesses requiring highly stable environments and upgrade paths. In contrast, while MariaDB is fully open-source and more community-driven, it also offers commercial support through MariaDB Corporation, although it may not be as widely integrated with enterprise software as MySQL.
-
JSON Handling:
MySQL processes JSON data as binary objects, allowing for faster query execution and data retrieval when working with JSON data types. This is particularly useful for applications that heavily rely on JSON for data storage and retrieval. In contrast, MariaDB stores JSON as strings, which can be less efficient.
-
Compatibility with Oracle and Commercial Software:
MySQL is better integrated with Oracle products and has better compatibility with a wide range of commercial software, including ERP and CRM systems.
This is partly due to its long-standing popularity and the fact that many enterprise solutions are built with MySQL in mind.
-
Community vs. Corporate Influence:
MariaDB, being community-driven, tends to adopt new features more rapidly, which can appeal to developers looking for cutting-edge functionality. However, this also means it may be less stable for users who prioritize long-term stability over new developments. MySQL, with its backing from Oracle, offers a more measured development approach, focusing on delivering well-tested, stable releases, particularly in the enterprise version.
Which to Choose?
MariaDB is a strong choice for users seeking more flexibility, better performance in certain areas (e.g., thread pooling and replication), and a fully open-source solution with a faster rate of feature adoption. It supports a broader range of storage engines, making it ideal for applications with specific performance needs.
MySQL, on the other hand, may be better suited for users who prioritize stability, commercial software compatibility, and the ability to access robust enterprise support.
