Redis is the most popular NoSQL database, and one of the most popular databases overall.
Because it holds all data in memory and because of its design, Redis offers low- latency reads and writes, making it particularly suitable for use cases that require a cache. Redis ( / ˈ r ɛ d ɪ s/ Remote Dictionary Server) is an open-source in-memory storage, used as a distributed, in-memory key–value database, cache and message broker, with optional durability.
