You have already some existing users data in Cassandra? In that
case, you can implement federation provider, so your users will be
visible to Keycloak and imported into Keycloak internal storage. If
you want to store all core model data in Cassandra (realms, users
etc), we don't have support for that though. We have just JPA and
Mongo support now. I wonder if you can't use JPA model to store data
into Cassandra?<br clear="none">
