Data Distribution Algorithms: Modulo and Consistent Hash Implementations in Java

The article introduces a Java HashNodeService interface and demonstrates two data distribution algorithms—simple modulo hashing, which evenly spreads keys but remaps them heavily when nodes change, and consistent hashing with optional virtual nodes, which maintains balanced placement and high cache‑hit rates despite topology adjustments.
