WebSep 29, 2010 · In Consistent hashing , we visualize list of all nodes in a circular ring . (Basically a sorted array) start func For each node: Find f (node) where f is the hash function Append each f (node) to a sorted array For any key Compute the hash f (key) Find the first f (node)>f (key) map it end func. 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. Each slot is then represented by a server in a distributed system or cluster. The addition of a server and the removal of a server (during scalability or out… mbt mechanical https://zemakeupartistry.com
