Redis Practice Exam

Redis  or Remote Dictionary Server is an software which is open-source, in-memory data structure store used as a database, cache, and message broker. The software  offers high performance, low latency, and many data structures like strings, hashes, lists, sets, and sorted sets. Redis provides flexibility, scalability, and support for real-time applications, and used for caching, session management, pub/sub messaging, analytics, and more.
