Redis

Redis is an in-memory data store that acts like a high-speed database, cache, and message broker. It stores data in the computer's RAM for rapid access, making it ideal for applications that require quick response times, such as real-time analytics, gaming, or session management. Unlike traditional databases that save data on disk, Redis keeps data in memory, allowing it to read and write information almost instantly. It supports various data structures like strings, hashes, lists, and sets, providing flexibility for different types of data and use cases.
