Other features favoring Percona include the following:
#MARIADB VS MYSQL CODE#
On their website, Percona claims to be closer to the base MySQL code from a compatibility point of view and more conservative than MariaDB. Their features tend toward performance, availability, and scalability improvements for the largest databases with the highest throughput. Percona has concentrated on very demanding applications with their own high-performance alternative to the InnoDB storage engine called XtraDB, including instrumentation tools to tune it. It is appropriate for large multi-server VPS hosting applications, especially those with changing query patterns that can take advantage of MariaDB’s optimizer. Overall MariaDB is a mature future-looking branch of MySQL that aims to offer new features and advancements for the database. For example, it is possible to replicate from MySQL 5.6 into MariaDB 10.X, but not the reverse. The interaction of the Global Transaction IDs between MariaDB and MySQL might require careful implementation if you plan to have complex replication schema bridging MySQL flavors.MariaDB offers scalability features including multi-source replication, allowing a single server to replicate from several sources.As of version 10.1, MariaDB offers on-disk database encryption.It also includes Percona’s XtraDB as an option. MariaDB includes a larger array of storage engines than either MySQL base or Percona, including now a NoSQL option with Cassandra.Some other features that distinguish MariaDB include the following: It’s a potentially better choice if you cannot determine what kind of queries your project needs regularly. MariaDB has pushed toward making advances with the query optimizer. The MariaDB fork leans toward expanding the breadth of MySQL’s capabilities and is less conservative about adding new features than Percona.

Percona has picked up some of the optimizations and thread pool improvements from MariaDB. For example, MariaDB offers the XtraDB engine from Percona. Despite being competitors, each fork draws from the open source code of the other. Applications that work with MySQL should also work with either of these forks. Both are built to be drop-in replacements of MySQL. When MySQL was acquired by Sun and then Oracle, groups left to start their own forks of the MySQL code. Also, because of the dual licensing model, certain applications require a commercial license. Many in the open source community consider Oracle a blocking force to the open source nature of the original project. Its weaknesses, in comparison to the other two databases, lie in its governance.
There is a large community of MySQL users and administrators, and, as a result, a large collection of information published for MySQL, both on the web and in print. The code base is very stable and reliable for the kind of web applications it was designed to support.
The Oracle version of MySQL is a common installation on many hosts, a part of the classic LAMP and WAMP stacks, and the default database for WordPress.
#MARIADB VS MYSQL FREE#
Although open source, it is owned by Oracle, who offers it as a free community edition under the GPL ( GNU General Public License) and as a commercially licensed version. It was developed as a high-availability, reliable database for web-based applications in the 1990s. MySQL is a widely known, very popular open source relational database management system (often abbreviated RDBMS). Image: MySQL / Licensed under CC BY-SA 3.0
