This document contains information about the compatibility of the PlanetScale CNDb with MySQL features.
While Vitess supports running instances of MariaDB, PlanetScale CNDb currently does not.
CNDb supports all core features of MySQL 5.7, including standard SQL statements and MySQL-specific commands. In general, you can issue queries against your database as if it were a MySQL database.
The PlanetScale CNDb uses Vitess to scale your database. This means that the PlanetScale CNDb only supports the same set of MySQL features as the latest version of Vitess.
To learn about what MySQL features Vitess supports, see the Vitess documentation.
