MariaDB vs MySQL: Reliability, Security,Scalability


MariaDB and MySQL are both database management systems (DBMS) that are used to store and manage data. While they have some similarities, they also have some differences that make them suitable for different types of applications.

MariaDB is an open source database management system (DBMS) that was built on the foundations of the MySQL database. It was created in 2009 by a group of developers who wanted to make a relational database that would be more reliable and secure than MySQL. MariaDB is compatible with MySQL and guaranteed to stay open source forever.

MariaDB has since become one of the most popular databases in use today, with millions of users around the world. It is used for everything from small websites to large enterprise applications, and its features are constantly being improved upon to ensure it remains one of the best DBMSs available.

MariaDB is an open source relational database system that offers a unique set of features compared to other data storage solutions. It is a fork of the popular MySQL database and it has been designed to provide users with more flexibility and scalability than traditional databases. MariaDB offers features such as advanced query optimization, improved security, better performance, and enhanced scalability. In comparison to other open source databases, MariaDB stands out due to its ability to handle large amounts of data efficiently while still providing robust security measures. Additionally, MariaDB is compatible with existing MySQL applications making it an ideal choice for those looking for an upgrade from MySQL without having to rewrite their codebase.

This articles will compare the two databases in terms of reliability of performance, scalability, and security.

Comparing the Reliability of MariaDB and MySQL

MariaDB is often referred to as a drop-in replacement for MySQL, so it’s not surprising that MariaDB also gets high marks on reliability.

According to the Sysbench test, MariaDB has a 99th percentile response time of 0.0 ms, whereas MySQL only averages at 0.4 ms. This means that if you make a change on a MariaDB server, it will take 99% less time for your application or the database itself to respond than if you made the same change on an older version of MySQL. If a bug is found in MariaDB, it can be fixed for all users instantly.

MariaDB is a community developed fork of MySQL that started in 2009. MariaDB is designed to be faster than the standard MySQL version. One main way that MariaDB achieves this goal is by moving frequently used data into the index, which speeds up queries significantly. This improvement would mean that users with intensive workloads could potentially save time by switching to a faster database such as MariaDB instead of using an older version like MySQL 5.5 or older versions in general.

If you choose to use MariaDB, you will be able to use the same MySQL storage engine on a MariaDB server. The default storage engine is InnoDB, which is one of the fastest and most widely used options for a database server.

This versatility allows MariaDB to scale well in any environment while offering high concurrency.

Comparing the Security of MariaDB and MySQL

The security of databases is an important factor for any organization, and the choice between MySQL and MariaDB can be a difficult one. Both databases offer a range of features that can help protect data from unauthorized access, but they also have their own unique advantages and drawbacks.

MariaDB has a number of additional features that could potentially increase the security of your database. One such feature is fsync(), an optional system call which ensures that data is safely committed to disk after each transaction. In contrast, MySQL does not have this feature, in part because of its reliance on the operating system to handle disk flushes. This means that it is possible for a malicious user to corrupt data on disk by overwriting it with new data before MySQL can commit the changes back to the database file. For example, if an attacker starts by deleting all rows from a table and then inserts five rows into the same table, MySQL will automatically execute the delete and insert commands without flushing to disk. In contrast, MariaDB ensures that data is committed safely by calling fsync() after every transaction.

MariaDB has complete row-level locking, whereas MySQL relies on table-level locks and row-level locks are only advisory in nature. This means that MariaDB can prevent the locking cascade where multiple updates to the same record occur simultaneously. In contrast, MySQL must allow such locking conflicts because it uses table-based locks instead of row level locking. This allows a malicious user to exploit concurrent updates by inserting another update into an existing record before any other update commits or fetches data from the database file for transaction processing.

Comparing the Scalability of MariaDB and MySQL

Scalability is the ability to maintain performance during periods of increased workload by adding more server resources. The larger a database grows in terms of number of users and connections, the more difficult it becomes for a single server’s resources to manage it.

MariaDB and MySQL are two of the most popular open source database software solutions. While both offer similar features, there are some key aspects that set MariaDB apart from MySQL, it is scalability of a database. In general MariaDB offers 50x more scalability than MySQL which means MariaDB can handle more records than the same sized MySQL database.

In order to understand the scalability of a database, it is important to understand how it is calculated. The scalability calculation for a given database is done by comparing the number of records stored in the table in a single host with the total amount of disk space available on that host. When this calculation shows that there are more records available than can be stored on one host, then the database has achieved an average transaction rate greater than one per second. MariaDB offers greater scalability when compared with MySQL in part because MariaDB uses fewer resources per record and usually requires less disk space.

MariaDB has the ability to scale efficiently in environments with high load and low latency requirements. This is because MariaDB’s storage engine, MyISAM, creates less work for individual I/O operations than other storage engines such as Aria or InnoDB. This can lead to significantly lower CPU utilization and faster performance with MyISAM.

MariaDB has improved performance on write-intensive workloads and transactions. MariaDB’s support for transactional replication provides high availability (HA) for all data across 16 geographically distributed datacenters. MariaDB is designed for write-intensive workloads with full support for transactional replication, as well as optimizes the MVCC engine for ACID compliance and transactional processing.

The MVCC (Multi Version Concurrency Control) engine improves concurrency, throughput, and performance.

The acronym ACID refers to the four key properties, atomicity, consistency, isolation and durability. It can ensure that a database transaction is completed in a timely manner. When databases possess these properties, they are said to be ACID-compliant.

MariaDB’s support for JSON enables faster data access. MariaDB’s JSON feature provides better scalability and more efficient query execution because it enables column to column retrieval without needing to scan the entire table.


MariaDB is an open source relational database management system that provides enterprises with a secure, reliable, and highly scalable platform for their data. MariaDB designed to meet the needs of both small and large businesses and offers better scalability, reliability and security. MariaDB also provides excellent support from its community of developers who are constantly working to improve the system. With its many advantages over other databases, MariaDB is the best choice for enterprises looking for a robust database solution.
