A preliminary understanding of Redis

Redis is an open source, advanced key-value storage and a perfect solution for building high-performance, scalable Web applications.

The three main features that Redis inherits from its many competitions are:

• The Redis database is completely in memory and uses disk for persistence only.

• Redis has a rich set of data types compared to many key-value data stores.

• Redis can replicate data to any number of slave servers.

It can be used as a database, cache, and message middleware.

It supports multiple types of data structures:

such as String (strings), hash (hashes), list (lists), collection (sets), ordered set (sorted sets) with Range query.
