Consistent Hashing Ring

A readable hash ring with virtual nodes and binary-search lookup, the core primitive behind cache and storage routing.

TypeScriptDifficulty: starter
$Read src/demo.ts and run it with any TypeScript runner.
Key Takeaways & Architecture Lessons
  • 01.Virtual nodes smooth uneven key distribution across physical nodes.
  • 02.The lookup is a binary search for the first ring point clockwise from the key.
  • 03.Adding a node remaps only a slice of keys instead of reshuffling everything.
