Redis (or remote dictionary server) is an open-source in-memory data store, NoSQL database that can be used primarily as an application cache or database.
Redis stores its data in memory so that it can deliver unparalleled speed, reliability, and performance. Because of its ability to deliver super-fast response time, Redis is commonly used on many websites like social media and gaming websites.
