What should I do to store sessions in the database? Is there a guide to do this? Should I implement any SPI?

We have support for using either Infinispan or a database (relational or Mongo) to store the user sessions when load balanced.

If performance is not a problem you can just go with storing sessions in the database. Otherwise go with Infinispan, see http://docs.jboss.org/keycloak/docs/1.2.0.Beta1/userguide/html/clustering.html for the details on how to configure that. To use a replicated cache instead of a distributed cache use the following config for Infinspan:

<subsystem xmlns="urn:jboss:domain:infinispan:2.0">
 <cache-container name="keycloak" jndi-name="infinispan/Keycloak" start="EAGER">
 <transport lock-timeout="60000"/>
 <invalidation-cache name="realms" mode="SYNC"/>
 <invalidation-cache name="users" mode="SYNC"/>
 <replicated-cachename="sessions" mode="SYNC"/>
 <replicated-cache name="loginFailures" mode="SYNC"/>

You can also just use the configuration from the docs above but set 'owners="2"'.
