Node.js module for performing fast rendezvous (HRW) hashing with skeleton - Can efficiently handle a large number of machines/sites.
This approach is slower than consistent hashing but provides much more even distribution of keys across sites - Particularly when there are a large number of sites and keys; the distribution gets progressively better as you add more keys. It can be configured to prioritize different features (e.g. distribution, performance, remapping %).
