[keycloak-dev] investigating caching

I think I have a decent way of doing caching, but it is going to take a refactoring of the Model API and KeycloakSession API so that caching can be layered (i.e. that we can cache realms/apps, but not cache users). For instance, the JPA adapter pretty much is hard-wired to have a loaded entity before it makes queries like "select user where user.realm = ? and user.name = ?". We need to move things like user queries up to the KeycloakSession level so that we can use things like EntityManager.getReference() so that we're not making extra DB calls if we need to query a user. -- Bill Burke JBoss, a division of Red Hat http://bill.burkecentral.com
