----------------------------------

             Summary: CacheStatusResponse map uses too much memory
                 Key: ISPN-4979
                 URL: https://issues.jboss.org/browse/ISPN-4979
             Project: Infinispan
          Issue Type: Bug
          Components: Core, State Transfer
    Affects Versions: 7.0.0.Final
            Reporter: Dan Berindei
            Priority: Critical
             Fix For: 7.1.0.Final


When the cluster is large and there are a log of caches, the {{CacheStatusResponse}} map on the new coordinator can get quite large. One of the problems that seems to be that the addresses in {{DefaultConsistentHash}} are duplicated on serialization, so the deserialized version occupies more memory.

We need to investigate why the objects are not "shared" by the River marshaller, and maybe work around the problem by de-duplicating the addresses in the externalizer.
