WebJan 13, 2010 · A dictionary is a data structure that maps keys to values. A hash table is a data structure that maps keys to values by taking the hash value of the key (by applying some hash function to it) and mapping that to a bucket where one or more values are stored. IMO this is analogous to asking the difference between a list and a linked list. 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.
