-We can enable the persistent sessions to be stored in the user-sessions and client-sessions into the target database in use. By default, the `KC_PERSISTENT_SESSIONS` is set to `false` in our benchmark provisioning module, we need to override it to `true` to enable this feature. Please note that, there will be a tax on the endpoint performance when you enable this feature and this is as designed, to provide better resiliency for Keycloak.
