Consistency hash algorithm and java implementation

Typical application scenarios are: N servers provide caching services, need to load balance the server, distribute requests to each server on average, and each machine is responsible for 1/N of the service. The commonly used algorithm is to take the remainder of hash result (hash() mod N): for machine numbers from 0 to N-1, according to the cu ...
