MariaDB includes a User Feedback plugin. When enabled, the plugin submits basic, completely anonymous MariaDB usage information. This information is used by the developers to track trends in MariaDB usage to better guide development efforts.
To help make MariaDB better, simply add “plugin-load=feedback.so” to your my.cnf file! On Windows, add “feedback=ON” to your my.ini file, or click the checkbox during the installation of the MSI package.
