Hmmm. Probably won't quite work for us - we need the timeToLiveSeconds behavior in LRU policy. To mimic that, we'd need to set a new ExpirationPolicy time on every get, which would kill performance (due to replication).
One thing that I'm thinking is adding a ClusteredCacheLoader. So if one server evicts too soon (due to node having been read on a different server recently), the ClusteredCacheLoader will get it from the other cache. When a node is evicted on all servers in the cluster, then it's when we really wanted to evict.
Does that sound like it might work? Question about ClusteredCacheLoader, since I've never used it. If we've got 4 servers in the cluster, and a node has been evicted from 3 of them, are we okay? Does the ClusteredCacheLoader search all other servers in the cluster until it finds the node?
