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?Hi,
My core backend system use Cassandra and Elasticsearch, running on Wildfly 9.
I need to change keycloak data store implementation to use Cassandra instead of MySQL and MongdoDB.
We have themes support. See documentation and examples.I need also change login, sign up to fit with my web app.
