Roles in MariaDB follow the SQL Standard implementation. Roles are a very useful feature for ensuring ease of use for a DBA. Not only that, but thanks to DEFAULT ROLE, applications not previously aware of roles can make use of them transparently.
In this talk we will cover the following aspects of Roles: * Creating, granting, activating. * Roles granted to roles (the role graph) * Default Roles * Information schema tables * Differences to MySQL, migration with mariadb-dump.
