Install MariaDB 10.6 on CentOS 7

MariaDB is a commonly used OpenSource database mainly known for being robust and scalable with new storage engines. MariaDB is a development of MySQL which puts focus on stability and performance and makes it free to users. It is the default database in most Linux distributions. With a variety of tools and plugins, MariaDB is widely applicable.

Features of MariaDB 10.6

MariaDB 10.6 is the current stable version of MariaDB and comes with a number of new features as discussed below:

  • Ignored Indexes – These are indexes that are visible and maintained but not used by the optimizer
  • sys schema supported- This is a “system” database containing views and procedures for investigating performance problems.
  • SKIP LOCKED – Locked tables are skipped from being updated or selected.
  • JSON_TABLE() – can create a JSON table that can be used as a subquery from a JSON document.
  • OFFSET…FETCH…[WITH TIES] – WITH TIES is an optional clause that adds extra functionality. Example as used
  • Oracle compatibility – There are ongoing works in making MariaDB compatible with OracleDB with some Oracle Syntaxes and functions already added.

The Improvements in MariaDB 10.6 from MariaDB 10.5 include:

  • Atomic DDL – CREATE, ALTER, DROP and RENAME are atomic and crash-safe. If the MariaDB server crashes while processing any of these operations, the change will either e done completely or not done at all.
  • InnoDB improvements – First insert to an empty table is faster. Also writes to temporary tables are avoided. Faster implicit and explicit temporary tables.
  • Improvements in Galera. Ability to enable encrypted connections between two nodes without downtime. Also added flags to specify if Galera’s controversial compatible features should be enabled.
  • Clean up to remove unsupported features such as TukoDB Engine, Cassandra Engine, some InnoDB variables, and some innodb_checksum_algorithm.
