What is Redis?
Redis is an in memory data store that functions as a database, cache, and message broker. Its pub/sub messaging model lets applications publish messages to channels and have them delivered instantly to subscribers, making it a common choice for real time notifications, chat features, and event driven microservices. Redis supports data structures such as strings, hashes, lists, sets, sorted sets, and streams, along with optional persistence through snapshots and append only file logging.
Redis is available as free, self hosted open source software and as Redis Cloud, a fully managed service with a free tier and paid Essentials and Pro plans priced by memory and throughput. Redis is developed by Redis, a company headquartered in the United States, and is used for caching, session storage, real time analytics, and messaging in applications of many sizes.
