Describe the Bug

Hi all,

Magento 2 configuration for MariaDB does not follow Adobe recommendations.
Specially visible on large projects.

Please see
https://experienceleague.adobe.com/en/docs/commerce-cloud-service/user-guide/configure/service/mysql
under "Configure MySQL database".

Please add following configuration for MariaDB
optimizer_switch: "rowid_filter=off"
optimizer_use_condition_selectivity: 1

Not setting those variables result in x10 or x20 order of magnitude in reindexing time for Category products alone.
Also seen unproperly configured on many production webshops
