MariaDB 10.1 is a drop in replacement for MySQL 5.5 and is available when creating new databases. It brings with it a lot of new features and optimizations to help speed up queries!
Previously, Cloud Sites was going to update users to MariaDB 10 but with 10.1 available and stable for the platform. All ORD databases will, instead, be updated to MariaDB 10.1 starting in September. Users can migrate their databases to the new option ahead of time and are encouraged to do so.
We’ve prepared an easy-to-follow guide on how to self-migrate here.
