             Summary: Restore predefined cache limitation for Hot Rod servers
                 Key: ISPN-4296
                 URL: https://issues.jboss.org/browse/ISPN-4296
             Project: Infinispan
          Issue Type: Enhancement
          Components: Remote Protocols
    Affects Versions: 7.0.0.Alpha3
            Reporter: Galder Zamarreño
            Assignee: Galder Zamarreño
             Fix For: 7.0.0.Beta1


Even after asymmetric cluster support was implemented, each node still does not know which other nodes contain which caches. The coordinator of the cluster knows, but no one else. This is because the aim has never really been to have different nodes containing different caches, but more about making sure that caches can be started lazily. With this in mind, the limitation in ISPN-833 will be reinstated.

Being able to work only with predefined caches also simplifies a solution for ISPN-3530 because we can safely assume that all servers contain the defined caches. Each cache might have a different consistent hash (see dev list discussion on why this can easily happen - ) but at least knowing that the nodes that have it is the same makes it easier to come up with a solution.

Finally, restoring the limitation avoids other can of worms such as the edge cases discovered by Jakub in ISPN-4212.
