> If a cache instance with a cache store is down and the cache is changed until the instance is back and join the cluster the cache can become inconsisstent.
> If entries are deleted during downtime,
> - the FileStore with stale object is loaded first if preload=true
> - the local entries are updated with new and changed objects from the cluster
> - removed entries from the cluster are not seen and therefore not deleted
> After complete sync (only) this instance will have stale objects.
> From a consistence and performance perspective the FileStore should be pruned on cluster-join by default in this case
