[keycloak-user] Keycloak 2.5.4 - persistence of replicated cache Session to file ?

Hello, We want to keep the sessions after a restart of an entire cluster of keycloaks. Can we store the data of the sessions caches (and maybe others) to a file ? The purpose here is if the cluster goes down, he can recover sessions from files. So the restart can be the more transparent to the client. ANTOINE CHOIMET Ingenieur d'Etudes et Developpement
