Rehashing and state transfer to use digesting
---------------------------------------------

                 Key: ISPN-1195
                 URL: https://issues.jboss.org/browse/ISPN-1195
             Project: Infinispan
          Issue Type: Feature Request
          Components: Distributed Cache, State transfer
    Affects Versions: 5.0.0.FINAL
            Reporter: Manik Surtani
            Assignee: Dan Berindei
            Priority: Critical
             Fix For: 5.1.0.BETA1, 5.1.0.Final


Rather than pushing entire state to new joiners, a mechanism of digests should be used to minimise network transfers.  For example, Merkle trees can be used to determine which entries are out of date and need pushing, in the case of nodes that persist to a local cache store, and is restarted but still has access to some state on disk.

This would require versioned entries though.
