MariaDB and MySQL are two of the most popular relational database management systems (RDBMS). Both originated from the same source code but have diverged significantly over the years, each with its unique features, performance improvements, and use cases. This guide provides a comprehensive comparison between MariaDB and MySQL to help you decide which is the better choice for your needs.
Table of Contents
History Of MariaDB vs MySQL
MySQL
- Released: 1995 by MySQL AB.
- Acquisition: Acquired by Sun Microsystems in 2008, which was later acquired by Oracle Corporation in 2010.
- Current Owner: Oracle Corporation.
MariaDB
- Fork: Created in 2009 by the original MySQL developers as a response to Oracle’s acquisition of MySQL.
- Current Maintainer: MariaDB Foundation, an independent organization ensuring the software remains open-source.

Licensing
- MySQL: Dual licensing model – GPL (open source) and commercial licenses.
- MariaDB: Entirely open source under the GPL license. This provides transparency and eliminates potential licensing costs or restrictions.
Compatibility
- Origin: MariaDB started as a direct drop-in replacement for MySQL.
- Data Files: Compatible up to MariaDB 10.4. Post 10.4, certain features may require additional adjustments to ensure compatibility.
- API and Protocols: MariaDB retains compatibility with MySQL clients and connectors, though some MariaDB-specific features are not backward-compatible.
Performance
MariaDB
- Storage Engines: Supports additional engines like Aria, ColumnStore, and MyRocks.
- Thread Pooling: Enhanced multi-threading capabilities, beneficial for high-concurrency environments.
- Query Optimization: Advanced query optimizations compared to MySQL.
MySQL
- Default Engine: InnoDB is the most commonly used storage engine.
- Performance Schema: Provides robust insights for performance tuning.
- Enterprise Features: Oracle’s commercial editions include additional performance-related features.
Features of MariaDB vs MySQL
MariaDB
- Dynamic Columns: Allows you to store diverse types of data in a single table.
- JSON Functions: Extended JSON support compared to MySQL.
- Parallel Replication: Improves replication performance.
- Encryption: Built-in encryption for tables and logs.

MySQL
- Document Store: Allows for NoSQL-like capabilities.
- Group Replication: Offers high availability and failover solutions.
- Oracle Integration: Enterprise support and tools for Oracle ecosystems.
MariaDB vs MySQL: Community and Support
MariaDB
- Community: Vibrant open-source community with frequent updates.
- Foundation: Independent foundation ensures long-term viability.
MySQL
- Community: Supported by Oracle with extensive documentation.
- Commercial Support: Oracle provides premium support for enterprise users.
Use Cases
When to Use MariaDB
- Open-source projects where transparency is critical.
- Applications requiring advanced storage engines or high concurrency.
- Systems needing advanced query optimization features.
When to Use MySQL
- Enterprises already invested in Oracle’s ecosystem.
- Projects needing long-term support and enterprise-grade features.
- Applications requiring NoSQL capabilities through Document Store.
Summary Table
| Feature | MariaDB | MySQL | 
|---|---|---|
| License | GPL (Fully Open Source) | GPL and Commercial | 
| Performance | Advanced query optimization, thread pool | Strong performance schema | 
| Storage Engines | Aria, ColumnStore, MyRocks, InnoDB | InnoDB, MyISAM | 
| Compatibility | Compatible up to MySQL 5.7 (mostly) | Industry-standard compatibility | 
| Community | Independent, open-source-focused | Oracle-supported | 
| Key Features | Dynamic columns, parallel replication | Document Store, group replication | 
Conclusion
Choosing between MariaDB and MySQL for your hosting service depends on your specific needs and priorities. If open-source commitment and advanced features are critical, MariaDB is a strong contender. Conversely, if you require enterprise-grade tools and Oracle ecosystem integration, MySQL may be the better option.
