Cloudflare cut 100TB of RAM by re-deriving the consistent hashing math behind a 2007 default. What the formula, and a Rust alignment gotcha, mean for
Add one server under naive hash%N and most keys move for no reason. This post builds a real consistent hashing ring, measures how much less it reshuffles, then covers the load-balancing problem that ring-based hashing introduces and how virtual nodes, weighted for mismatched hardware, fix it.
