redis Redis Set Datatype
Introduction
Redis supports a set datatype analogous to mathematical sets for modeling data in the database. Sets are a compound datatype consisting of a group of unique, unordered members. Sets support adding and removing members, size operations, as well as combination operations that take two sets and generate a third set. Sets in Redis are similar to Sets in most programming languages.
