What is the main benefit of consistent hashing for shard routing?

Problem Statement

Explanation

Consistent hashing maps keys to a ring so only a fraction of keys remap on topology change, easing resharding. Evenness improves with virtual nodes, but perfect balance is not guaranteed without monitoring.

Code Solution
