redis: Redis (Key-Value Store) redis: redis: Redis is an advanced key-value store. It is similar to memcached but redis: the dataset is not volatile, and values can be strings, exactly like redis: in memcached, but also lists, sets, and ordered sets. These data redis: types can be manipulated with atomic operations to push/pop elements, redis: add/remove elements, perform server side union, intersection, redis: Records are organized in hash table, B+ tree, or a fixed-length array. redis: Redis supports different kinds of sorting abilities. redis: redis: Homepage: http://redis.io/
