WebA consistent hash is a hashing technique where most keys will not need to be reamapped if the number of slots in the table changes. On average, only k/n keys will need to be remapped for a system where k is the number of keys and n is the number of slots in the table.

WebApr 5, 2024 · Consistent hashing is a special kind of hashing whereby when the hash table is resized, only a small portion of the data needs to be moved. Specifically, the number of data items that need to be moved is n/m, where n is the number of data items, and m is the number of rows in the hash table (or servers, in our earlier distributed system example).

The term "consistent hashing" was introduced by David Karger et al. at MIT for use in distributed caching, particularly for the web. This academic paper from 1997 in Symposium on Theory of Computing introduced the term "consistent hashing" as a way of distributing requests among a changing population of web servers.
