Ring
Noun · Development
Definitions
A circular data structure or topology in which elements are arranged in a loop so that traversal from the last element wraps to the first. In distributed systems, a hash ring maps keys to nodes using consistent hashing, minimizing redistribution when nodes join or leave the cluster.
In plain English: A circular arrangement where the end connects back to the beginning, often used to evenly spread data across multiple servers.
Example: "When a Cassandra node goes down, the ring redistributes its token range to the adjacent replicas."
