Redis is an open-source, in-memory data structure store used for caching, messaging, and real-time data processing. It supports a wide range of data structures, including strings, hashes, lists, sets, and sorted sets. Redis is designed to be extremely fast and efficient, with low latencies and high throughput. It also provides advanced features such as replication, pub/sub messaging, Lua scripting, transactions, and cluster support. Redis is widely used in web applications, gaming, IoT, and other use cases where fast and scalable data processing is required.
