Redis is an advanced key-value store. It is often referred to as a data-structure server since keys can contain strings, hashes, lists, sets, and sorted sets. For performance, Redis works with an in-memory data set. You can persist it either by dumping the data set to disk every once in a while, or by appending each command to a log.
