MariaDB is a community-driven fork of MySQL, and is a relational DBMS that can be used to build reliable, high-performance database servers. MariaDB combines MySQL characteristics such as replication, backup and disaster recovery, transactions and locks, and also includes important improvements to the performance, stability, security, and monitoring capabilities.Mastering MariaDBstarts with an overview of the basic features and mechanisms, which includes diagnosing and solving real-life problems such as data corruption, poorly performing queries, and deadlocks. You will learn how to improve the performance of a server by identifying slow queries, and how to choose and set up a proper backup plan and recover data when disasters occur. You will learn how to share your data through several servers using replication. By the end of this book, you will be able to configure MariaDB servers, diagnose as well as troubleshoot common transactional problems, and execute database maintenance.
