Consistent Hashing Ring

Consistent hashing ring simulator with virtual nodes and rehash avalanche analysis.

Key Distribution (80 Total Keys)
Node A 20 keys (25.0%)
Node B 20 keys (25.0%)
Node C 20 keys (25.0%)
Node D 20 keys (25.0%)
💡 Why Virtual Nodes Matter: With 1 node per server, hash clustering causes major data skew (avalanche). Adding virtual nodes (e.g. 15+) balances the keys evenly around the ring, reducing standard deviation by over 80%.
