We would like to ask update in following documentation:
https://access.redhat.com/documentation/en-us/red_hat_3scale_api_management/2.11/html-single/installing_3scale/index#configure-external-mysql-database
Chapter 8. Configuring an external MySQL database
8.2. Externalizing the MySQL database
9. Create a default 'user'@'%' on the remote MySQL database. It only needs to have SELECT privileges. Also find its base64 equivalents:
"It only needs to have SELECT privileges"

Change "It only needs to have SELECT privileges" =>
TO "Required user privilages: ALL PRIVILEGES"

The reason for requested change in 2.15 documentation (maybe add it also to documentation?):
In 3scale release 2.16 (future/next release) - the secret `system-database` is planned to be changed:

• DB_USER and DB_PASSWORD fields will be removed from the secret
• URL will be changed - `root` user will be replaced with regular user (that is in DB_USER field)
  This user should have grants to allow full access for the system app to create tables, update tables etc.
  This will allow to avoid use `root` user in 2.16, and have `system-database` secret more simple for usage and understanding.
