Remote Dictionary Server, commonly known as REDIS is a free and open-source, in-memory data storage and caching system.
You will often hear developers referring to Redis as data structure server as it allows us to store, manipulate, and retrieve data structures from system memory.
Redis is designed to be a high-performance and low-latency data access system which makes it extremely suitable as a caching mechanism or environments where fast data retrieval is essential. An example would be real-time analytics, session management, queing systems, etc.
