MySQL is the popular and ubiquitous database at the core of may Moodle installation. MySQL 5.6 has been our most popular release but 5.7 is on the way with improvements in security, performance, and manageability. You can now have a secure by default installation (no anonymous accounts or root accounts with no passwords), password rotation, and pluggable authentication. Tools like MySQL Fabric provide robust highly available server farms or the ability to shard without changing Moodle. But with these changes there are some things, like a default SQL Mode of STRICT, that may break some tools (like Wordpress). This session will cover the major changes in MySQL 5.7 and show you how to best use them to your advantage, work arounds for common upgrade issues, and show you where you might get into difficulty with the latest release.
