Redis

Meet Redis

Redis is an in-memory data store used to make applications respond quickly and handle frequently changing information. Developers use it for caches, login sessions, leaderboards, and event-driven workflows. Its native data structures include strings, hashes, lists, sets, and streams, while JSON support and vector search expand the kinds of application data it can manage.

Redis can serve as a fast layer alongside another database or hold application data with configurable disk persistence. Teams can run the open-source edition themselves, choose managed Redis Cloud, or deploy Redis Software in their own infrastructure. Client libraries connect it to common programming languages, making it practical for web services, messaging systems, and search features that need timely access to data.
