Thank you Gabriel for the detailed response!
May I ask how many KC servers are using for the 500-600 tenants setup?
Regards,
Raanan

Subject: Re: [keycloak-user] Multi Tenant Keycloak Scale
Hi Raanan,
we've hit many issues on our side with a large number of realms and took some
time to study and fix them. I suggest you to have a look at this thread in the dev ML:
http://lists.jboss.org/pipermail/keycloak-dev/2016-November/008439.html
I have 5 pull requests that were submitted, 2 merged and 3 still pending for the 3.x
release. For now, we're running an in-house Keycloak build with those fixes.
There could still be some areas that are not covered by my pull requests that we
haven't hit yet.

Hi,
We are using Keycloak 1.7 for multi tenant environment where each tenant is a realm.
We have a cluster of 4 Keycloak servers and we see severe performance degradation when we
are using about 200 Realms with 200 users each.
Is that the expected behavior of Keycloak?
Are there known issues with such an amount of realms in Keycloak 1.7?
What should we do to be able to work with much more realms (we need about 2000)?
Thanks,
Raanan
