The linked thread pertains to cache loaders. There can be only one cache loader per thread. What's confusing to me (and probably to others) is why do you need to segregate the data into separate cache instances, and what is the point of copying all the caches' data into one core cache? If you wanted, though, one approach would be to wrap multiple TcpDelegatingCacheLoader into a single CacheLoader. Then configure your "core cache" to use this cache loader.
