When MySQL was acquired by Oracle in 2010, the original creator Monty Widenius forked the project to create MariaDB. Since then, both databases have evolved in different directions. This comparison helps you understand where they stand in 2026 and which one best fits your needs.
History and Governance
MySQL
Owned and developed by Oracle Corporation. Available in Community Edition (GPL) and Enterprise Edition (commercial license). Oracle controls the development roadmap and release schedule.
MariaDB
Maintained by the MariaDB Foundation and MariaDB Corporation. Fully open-source with GPL licensing. Community-driven development with corporate backing.
Feature Comparison
| Feature | MySQL 8.x | MariaDB 11.x |
|---|---|---|
| Default Storage Engine | InnoDB | InnoDB (Aria for system tables) |
| JSON Support | Native JSON type | JSON alias for LONGTEXT |
| Window Functions | Yes | Yes |
| CTEs (WITH clause) | Yes | Yes |
| Columnar Storage | HeatWave (Cloud only) | ColumnStore engine |
| Oracle Compatibility | Limited | SQL_MODE=ORACLE |
| Temporal Tables | No | Yes (System-versioned) |
| Invisible Columns | Yes (8.0.23+) | Yes |
| Thread Pool | Enterprise only | Included (free) |
| Encryption at Rest | Enterprise/Community | Included (free) |
| Audit Plugin | Enterprise only | Included (free) |
| GIS/Spatial | Good | Good |
| Replication | Group Replication | Galera Cluster |
When to Choose MySQL
- Cloud-managed databases — AWS RDS, Google Cloud SQL, and Azure Database have excellent MySQL support
- Existing MySQL applications — If your application was built for MySQL, staying is the path of least resistance
- Oracle ecosystem — If your organization already uses Oracle products
- JSON-heavy workloads — MySQL's native JSON type is more feature-rich
When to Choose MariaDB
- Open-source commitment — All features are available in the free version
- Advanced features without cost — Thread pool, audit logging, encryption included free
- Oracle migration — SQL_MODE=ORACLE helps migrate from Oracle databases
- Temporal tables — System-versioned tables for data history tracking
- Galera Cluster — Mature multi-master replication solution
Performance Comparison
In typical OLTP workloads, MySQL and MariaDB perform similarly. However:
- MySQL 8.x has a slightly better query optimizer for complex joins
- MariaDB's thread pool gives it an advantage under high concurrency (100+ connections)
- MariaDB's Aria engine provides faster temporary table operations
- Both handle millions of queries per second on modern hardware
Compatibility Status
MariaDB and MySQL have been diverging for years. While basic SQL and client tools remain compatible, advanced features increasingly differ. Applications using MySQL-specific features like X Protocol, MySQL Shell, or Group Replication will not work on MariaDB without modification.
The Verdict
Both databases are excellent choices for production use. The best choice depends on your specific requirements, team expertise, and licensing preferences. For new projects, also consider PostgreSQL as a third option — it offers many features that neither MySQL nor MariaDB match.
