chash

This library provides a consistent hashring which simultaneously achieves both uniformity and consistency. It is a direct port of the Go pkg https://github.com/buraksezer/consistent.

For detailed information about the concept, you should take a look at the following resources:

• Consistent Hashing with Bounded Loads on Google Research Blog
• Improving load balancing with a new consistent-hashing algorithm on Vimeo Engineering Blog
• Consistent Hashing with Bounded Loads paper on arXiv

Wishlist

• Add benchmarks
• Moar tests! Especially property based testing
• async/await API
• Pluggable storage w/ implementations: in-memory (possibly w/ DashMap), etcd, redis, and foundationdb
• Performance Tuning (mostly the obvious stuff... no quest for glory)
