--------------------------------------

             Summary: Clustered cache with FileStore (shared=false) is inconsistent after restarting one node if entries are deleted during restart
                 Key: ISPN-4908
                 URL: https://issues.jboss.org/browse/ISPN-4908
             Project: Infinispan
          Issue Type: Bug
         Environment: Clustered REPL cache, preloaded, no eviction/expiration
            Reporter: Wolf-Dieter Fink


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
