User permissions

In order to grant rudol the necessary permissions to fetch your database metadata we recommend you to create a new MariaDB user with access restricted only to the information_schema database.

Here is a sample code to create a new user for rudol with minimal permissions for metadata scan:

CREATE USER 'rudol_user'@'' IDENTIFIED BY 'super-secret-password';

GRANT SELECT ON information_schema.`COLUMNS` TO 'rudol_user'@'';
GRANT SELECT ON information_schema.`TABLES` TO 'rudol_user'@'';

If you want to use Data Quality features these permissions won't be enough: you'll have to grant SELECT to each table you'd like to run tests for, and CREATE TEMPORARY TABLE to run validations without locking tables.
