There are some drivers (Kundera, Datanucleus, spring cassandra, Hibernate OGM etc) that apparently use JPA to NOSQL conversion that I tried earlier with one project but didn't have a good experience and had to replace the entire persistence layer. On the same subject, if I were to do that (replace Mongodb with Cassandra), where should I start?

I need to change keycloak data store implementation to use Cassandra instead of MySQL and MongdoDB. 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? I need also change login, sign up to fit with my web app. We have themes support. See documentation and examples. Marek What is the best way to change as I mentioned above?     Best Regards, Sun Chanras _______________________________________________ keycloak-dev mailing list keycloak-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/keycloak-dev _______________________________________________ keycloak-dev mailing list keycloak-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/keycloak-dev
