We should try to enable the "Index Affinity" capabilities in an easier way from a configuration point of view.

For example I wonder if the capabilities provided by the AffinityPartitioner could not be enabled by default, for example automatically decorating any user defined HashFunctionPartitioner so that people can't neither forget to enable it, nor override it.

Second, should it be enabled by default when the cache configuration suggests it, for example in most clustered caches?
