Magento 2 MySQL

MySQL is one of the most in-demand databases for e-commerce websites due to the secure financial transactions that have data integrity, a possibility of the management of deeply embedded applications, and its consistent availability. However, by no means all merchants know Magento 2 basic requirements. 

Magento 2 MySQL specifications (Magento MariaDB and Percona)

Magento 2 is compatible with MariaDB*, Percona* and MySQL.
MySQL specifications:

• The latest Magento version doesn’t operate with MySQL 5.5 but MySQL 5.6.x and better will suit;
• Magento 2.1.2 and later versions are compatible with MySQL 5.7.x;
• MySQL triggers are used to enhance database accessibility during reindexing;
• If you need to import many products, you are able to increase the value for max_allowed_packet to make 16MB, which is larger than the default.

**MariaDB and Percona are compatible with Magento 2 due to the support of MySQL APIs.

Magento 2 MySQL Config

Learn it before adjusting MySQL to your store needs:

• you won’t be able to run any custom triggers, as they can introduce incompatibilities with future Magento versions;
• read about restrictions for MySQL triggers before making any changes;
• learn about replication formats supported by Magento 2, e.g.: the platform doesn’t support MySQL statement-based replication.
