-                Keycloak provides a JSON file based model implementation, which means that your identity data will be saved
-                in a flat JSON text file instead of traditional RDBMS.  The performance of this implementaion is likely to
-                be slower because it reads and writes the entire file with each call to the Keycloak REST API.  But it is 
-                very useful in development to see exactly what is being saved.  <emphasis>It is not recommended for 
-                production.</emphasis>

-                Note that this only applies to realm and user data.  There is currently no file implementation for
-                event persistence.  So you will need to use JPA or Mongo for that.
