Steve Shaw is the open source database lead for Intel and lead developer of the open source database benchmarking tool HammerDB. With more than 20 years experience in commercial database he is also the author of 2 books on Oracle on Linux. He now focuses exclusively on ensuring that open source relational database runs best on Intel platforms.


MariaDB Server is one of the most popular database servers in the world. The way the relational model works ensures that data tables, views and indexes are separate from the physical storage of the database. A Linux-based MariaDB Galera Cluster implementation was also developed to provide a synchronous multi-master cluster option for MariaDB users.

Porting and packaging MariaDB Server to different platforms and operating systems to keep it as widely available as possible.

Special Features

As MariaDB is community-driven software, it is managed by the MariaDB Foundation. The GNU GPL license allows open-source communities to participate in the development and documentation process and review any development decisions via the foundation’s public mailing list. Meanwhile, MySQL supports a native JSON data type and provides the SHA-2 authentication plugin and the validate_password plugin by default, while MariaDB doesn’t. MariaDB is still completely open-source, while MySQL now has closed-source modules.

  • No single person or company is able to dictate priorities or code to the community.
  • SQL isn’t a vast language, but it can be nuanced and, as its name suggests, highly structured.
  • A relational database management system is the upgraded version of a database management system .
  • MariaDB Server provides an Oracle syntax compatibility mode for running Oracle Database applications without change.
  • Ensure user experience with unified performance monitoring, tracing, and metrics across applications, clouds, and SaaS.
  • MariaDB providessubscription servicesanddownloadswith additional enterprise features.

Each of the SQL statements mentioned here have several more options and clauses each. We will cover these statements and others in greater detail in other articles. For now, though, you can learn more about them from experimenting and by further reading of the Knowledge Base online documentation. A downloadable PDF of much of the documentation is available here. This statement will delete all rows from the table books for the author_id given. To do a clean job of it, we’ll have to do the same for the authors table.

Introduction of MariaDB

When we create a table, we specify its storage engine or use the default one. It is possible to convert an existing table to another storage engine, though this is a blocking operation which requires a complete table copy. Third-party storage engines can also be installed while MariaDB is running. SQL Server vs MySQL is a hot argument since both are the two most popular database management systems out there.

What is MariaDB

The above image shows that the MariaDB command prompt has changed from none to the name of the database that has been selected. The above output shows that the Demo database is part of the list, hence the database was created successfully. Once you’ve identified what tables are in a database, you’ve started to wander into the domain of actual data.

Lastly, MySQL is easy-to-use and customizable – it features multiple user interfaces to cater to different preferences. Backed by the Oracle Corporation, MySQL offers excellent compatibility. It is supported by most hosting providers and over 20 operating systems, making it platform-independent.

It’s capable of reading and writing to any node at any time and multi-threads the slave for better performance. It’s got a feature known as Hot Standby which means no downtime during a failover because there simply is no failover. The first release of MariaDB, known as version 5.1, became available for production uses in early 2010. Versions 5.2, 5.3 and 5.5 followed, and then MariaDB 10.0 was released in 2014. It represented a change in the database’s classification scheme, as earlier release numbers were patterned after MySQL ones.

Dynamic and Static Variables

We don’t need to give a value for the author_id since that column was created with the AUTO_INCREMENT option. MariaDB will automatically assign an identification number. You can manually assign one, especially if you want to start the count at a higher number than 1 (e.g., 1000).

What is MariaDB

Some features that are only available in the MySQL Enterprise Edition are absent from MariaDB. However, as part of its enterprise database solution, MariaDB does offer alternative open-source plugins, like MaxScale for data masking. Switching from MySQL to MariaDB follows a standard installation procedure. You just need to run the mysql_upgrade tool to update the MySQL database’s privileges and event tables with MariaDB’s equivalents. For instance, MariaDB has kept MySQL’s naming conventions, structure, and data definition files. Additionally, it supports all MySQL connections, connectors, and ports.

What Is MariaDB Used For?

That’s doubly true when the balance sheet is on weak footing. As of March 31, the company had just $9.7 million of cash and short-term investments left. That is only one quarter’s worth of cash at the current burn rate. Further to that, MariaDB had $42.4 million of current assets while facing $56.0 million of current liabilities. It’s always a worrisome sign when a loss-making company has substantially more current liabilities than current assets. Last quarter, the company grew revenues to $13.5 million from $10.7 million in the same quarter of 2022.
