[keycloak-user] Multi tenancy with realms

Hi. I'm looking to use keycloak for a SASS service, using realms for multi-tenancy. There's a discussion on a previous thread about performance issues when there are lots of realms: http://lists.jboss.org/pipermail/keycloak-user/2016-October/008061.html I wanted to ask if there is some work done in that direction. If not, where can I start looking at so I can contribute? Also, I was wondering what would be the implications of using a custom user attribute to "emulate" multi-tenancy. (I would add a custom attribute, and make my microservices validate against it). I know it's not the ideal way, but would it be possible? Do you know of any considerations I should take into account?
