Dear Keycloak Team,

Since my architecture is designed to be based on Cassandra for primary storage backend and ElasticSearch for search functionality.

Where should I start, if I need to change code base of keycloak to use Cassandra and customize field required for login and registration.

For example. I don’t want to have “username” field in my registration page. We need only “firstName”,”lastName”,”email”, “password”, and “confirmPassword”.

I want to custome “keycloak-server.war”  to fit with my application.

Where can I get start to customize “keycloak-server.war”.

PS:Using Themes and SPI provide by keycloak is not enough to customize to fit my implementation.

Best Regards,

Sun Chanras
