> 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.
