CREATE USER - MariaDB Knowledge Base
https://mariadb.com/kb/en/create-userTo use it, you must have the global CREATE USER privilege or the INSERT privilege for the mysql database. For each account, CREATE USER creates a new row in mysql.user (until MariaDB 10.3 this is a table, from MariaDB 10.4 it's a view) or mysql.global_priv_table (from MariaDB 10.4) that has no privileges.

Persistent statistics stored on disk allow the statistics to survive server restarts, and provide better query plan stability.
