Using native persistence question

Silly question, if I have native persistence on and a node goes down for 
some time, say I have a partitioned cache with backups or a replicated 
cache, so that cache lives on in the other nodes, will the old node 
handle this correct when it comes back online again and throw away any 
old cache entries that are no longer valid that is has stored on disk 
and start using the correct new entries from the other surviving nodes ?

Hello, Mikael.

Yes, "old node" should handle this situation correctly.
