What Does Redis Mean?
Redis is an advanced key-value store, better known as a data-structure server.
It can be considered as a type of database which works with key-value pairs and uses main memory for storing data. Its use of main memory means that it is both fast and scalable, but may be confined by the capacity of the RAM.
It also has built-in persistence though snapshotting and journalizing to disk so it can be used as a No SQL database.
