How does Realm cache invalidation works in Keycloak

Getting advice
1

We are looking into how we can invalidate Realm cache on our local Keycloak instance. Few action steps that have been tried so far are:

  • Create N no. of realms and clients
  • Delete N number of realms

However, this does not seem to invalidate the cache(we think!) since the GET “/realms” endpoint loads pretty quickly (4.2s) than otherwise which usually take > 1minute. We’re dealing with more than 300 realms here.

Any insights on this would be helpful.
