> Programmable affinity either through:
>  
> 1) statically (e.g. annotating a certain field as the key for consistent hashing)
> - in our case this cannot be based on the hashCode() as the affinity requirement and object identity are not directly related
>  
> 2) dynamically (e.g. providing a overridable/annotatable consistentHashCode() function)
>  
> This would help to assign entities (in multiple Caches), which are needed together in the same nodes (to avoid remote lookups)
