Redis created by Salvatore Sanfilippo is an open source, in-memory data structure server with advanced key-value cache and store, often referred to as a NoSQL database. It is also referred to as a data structure server, since it can store strings, hashes, lists, sets, sorted sets, and more. The essence of a key-value store is the ability to store some data, called a value inside a key. This data can later be retrieved only if we know the exact key used to store it.
