[keycloak-dev] sticky sessions, clustering, and authentication

I was thinking a bit about performance in a cluster. Right now a client session is created whenever login is initiated. This ends up requiring the client session to be propagated to the cluster, either through a database insert/update or an infinispan replication. Then, with each authentication/required action step, another insert/update/replication. I was thinking we should have an AuthenticationSession that was in memory only. Then, once all authentication and required actions are finished, then create the usersession and client session. This would require sticky sessions though with a load balancer. -- Bill Burke JBoss, a division of Red Hat http://bill.burkecentral.com
