Hashing is the practice of taking a string or input key, a variable created for storing narrative data, and representing it with a hash value. The original motivation for consistent hashing (in 1997) was Web caching. Consistent hashing gave birth to Akamai, which to this day is a major player in the Internet, managing the Web presence of tons of major companies. The idea has real applications. It is something that will create inconsistency in data in the same data. As a result, there is no need to hit the server.
