We have implemented near cache, I have written a hotrod client program which first puts data in the cache, and then it retrieves it in a loop, with thread sleep of 1 second. First read hit is on the server, and then subsequent reads are from the near cache. Meanwhile, suppose, if the cluster crashes, or assume all the nodes on which the distributed cache was stored, they all crashed, what will I get when I do cache.get(key). Will the near cache be invalidated at all? What happens if servers are shut down appropriately, not abruptly??
