Hi Team, I found that the admin role in master realm will have all roles in xxxx-realm type client in master realm as composite. This design will have a lots of rows to be inserted into database. However, the admin role is targeted for super privilideged users to have all privilidges on all resources in keycloak server, there is rarely reasons to change this scenario. One observation is that when there is 6K realms in database, the getRole method of admin role would take more than *1 SECOND*. It will result in bad response for admin rest api. Benifit: We are allieviated from lots of database write/read, especially when realm number grows to thousands and more. We are more confident to support large number of realms. Drawbacks: we need carefully implement logics on the special admin role, multiple places needs work. Please let me know your concerns. Thank you! Regards, Mingjun Liu
