In this article, we will provide an overview of MariaDB and MySQL, compare their features and functionality, and evaluate their performance, scalability, security, reliability, compatibility, pricing, and licensing. By the end of this article, you will have a better understanding of which database system is right for your business needs.
History of MariaDB and MySQL
MySQL was originally created in 1995 by Michael Widenius and David Axmark while working at TcX DataKonsult AB. In 2008, Sun Microsystems acquired MySQL AB, the company that developed and marketed MySQL, for $1 billion. In 2010, Oracle Corporation acquired Sun Microsystems, including MySQL AB, for $7.4 billion.
Following Oracle’s acquisition, concerns were raised about the future of MySQL as an open source project. To address these concerns, Michael Widenius founded MariaDB Corporation in 2009 to develop a community-driven, open source fork of MySQL.
MariaDB was designed to be a drop-in replacement for MySQL, providing enhanced performance, scalability and security features. Today, MariaDB continues to be developed as an open source project and is widely used by businesses and organizations around the world.
MariaDB and MySQL have a similar database architecture, as MariaDB was originally developed as a fork of MySQL. Both systems use a client-server model, where the server manages data storage, processing, and retrieval, and the client sends queries and receives results. They also both use Structured Query Language (SQL) as the primary language for managing data.
One key difference between the two systems is that MariaDB utilizes a more powerful and efficient storage engine called Aria. Aria is optimized for multi-core processors and has better support for transactions and rollback. MySQL, on the other hand, uses the InnoDB storage engine, which is known for its reliability and support for foreign keys.
Storage and Processing
In terms of data storage and processing, both MariaDB and MySQL use a hierarchical system of databases, tables, and columns. They both support indexes to speed up queries and provide efficient access to data. MySQL also supports partitioning, which allows for large tables to be split into smaller, more manageable pieces.
MariaDB is known for its superior processing speed due to its optimized storage engine. It also has a feature called Thread Pool, which helps to handle multiple client connections more efficiently. MySQL, on the other hand, has better support for complex queries and large datasets due to its use of InnoDB.
Both MariaDB and MySQL support replication, which allows for data to be copied between servers for backup, failover, and load balancing purposes. MariaDB has a more advanced replication system called Galera Cluster, which allows for synchronous multi-master replication, while MySQL supports master-slave replication.
Features and Functionality
MariaDB and MySQL both offer a wide range of features and functionality that are essential for modern database management. However, there are some key differences between the two systems that may influence which one you choose for your business needs.
Both MariaDB and MySQL have strong support for SQL, ensuring compatibility with a wide range of tools and applications. However, MariaDB has added several new features to SQL that are not available in MySQL. These include window functions, common table expressions, and JSON functions, which can be useful for data analysis and manipulation.
Storage engines are an essential component of any database system, as they determine how data is stored and accessed in the system. MariaDB and MySQL both support a variety of storage engines, but MariaDB has some notable advantages here. For example, MariaDB supports the Aria storage engine, which is optimized for temporary tables. It also supports the XtraDB storage engine, which is a high-performance version of InnoDB that includes additional features like online backups and crash recovery.
Both MariaDB and MySQL support replication, which allows you to create multiple copies of your database for load balancing, failover, or backup purposes. However, MariaDB has some advantages here as well. For example, MariaDB supports multi-source replication, which allows you to replicate data from multiple databases into a single database. It also supports delayed replication, which can be useful for recovering from accidental data deletion or corruption.
Plugins and Extensions
MariaDB and MySQL both support a variety of plugins and extensions that can extend the functionality of the system. However, MariaDB has some unique plugins that are not available in MySQL. For example, MariaDB has a plugin for connecting to the Cassandra NoSQL database, which MySQL does not support natively. It also has a plugin for using Spider, a powerful engine for sharding and federated data storage.
In summary, both MariaDB and MySQL offer a wide range of features and functionality that are essential for modern database management. However, MariaDB has some unique advantages in terms of SQL compatibility, storage engines, replication, and plugins. Depending on your specific business needs, one of these systems may be a better fit for your organization.
Performance and Scalability
When it comes to database systems, performance and scalability are critical factors to consider. MariaDB and MySQL have both been designed to handle large amounts of data and high numbers of concurrent transactions. However, there are some differences in how each system performs under different workloads.
MariaDB and MySQL are both known for their speed in handling database operations. MariaDB, however, is often considered to be faster than MySQL due to its use of the Aria storage engine. Aria is a crash-safe replacement for MyISAM, the default storage engine used by MySQL. It is designed to provide better performance and data reliability.
In terms of memory usage, both MariaDB and MySQL are similar. However, MariaDB has been optimized to use memory more efficiently than MySQL. MariaDB uses the TokuDB storage engine which has built-in compression and can store more data in memory. This means that MariaDB is better suited to handle workloads with large amounts of data.
Both MariaDB and MySQL use disk space to store and retrieve data. However, MariaDB has been optimized to use disk space more efficiently than MySQL. MariaDB uses the XtraDB storage engine, which is an enhanced version of InnoDB, the default storage engine used by MySQL. XtraDB provides better performance and data reliability, while also using disk space more efficiently.
Both MariaDB and MySQL are designed to handle different types of workloads. MariaDB performs well with OLTP workloads and high-availability systems. In contrast, MySQL is better suited to handling heavy read workloads, like those found in data warehousing and business intelligence applications.
Ultimately, the performance and scalability of a database system will depend on the specific needs of your business. Both MariaDB and MySQL have their strengths and weaknesses, and the best choice will depend on your workload and budget.
Security and Reliability

Migration and Compatibility
Migrating from one database system to another can be a challenging process. When considering a move from MySQL to MariaDB, it is important to understand the compatibility issues that may arise.
MariaDB is designed to be a drop-in replacement for MySQL, meaning that it is designed to be compatible with MySQL at the application level. This means that applications designed to work with MySQL should work seamlessly with MariaDB without requiring any code changes.
However, there are some differences between MariaDB and MySQL that can affect compatibility. For example, MariaDB introduces new features that are not present in MySQL, which may cause issues if an application relies on specific MySQL features that are not present in MariaDB.
It is important to test your application thoroughly to ensure that it works correctly with MariaDB before making the switch.
Migrating from MySQL to MariaDB involves exporting MySQL data into a format that can be imported into MariaDB. The easiest way to do this is to use the mysqldump command to export a MySQL database to a SQL file, and then import that file into MariaDB using the mysql command.
It is important to ensure that any database features that are used in the MySQL database, such as stored procedures or triggers, are compatible with MariaDB before attempting to migrate the data.
In some cases, it may be necessary to make changes to the application code to ensure compatibility with MariaDB. For example, some applications may use specific MySQL commands that are not supported by MariaDB, and these commands may need to be replaced with equivalent MariaDB commands.
Migrating from MySQL to MariaDB can be a complex process, but by understanding the compatibility issues and following best practices for migration, it is possible to make a smooth transition to the new system.
