Reason: High Performance: Store data in memory for fast access. Low latency: Optimized data structures and operations to minimize latency. Scalability: Easy to shard and cluster to adapt to high loads. Durability: Data can be persisted to disk to ensure data security. Rich features: Provides multiple data types, multi-level caching and publish/subscribe functions.
Redis as a cache server
Redis is an open source, high-performance, distributed key-value store that is Widely used as a cache server. It provides fast, reliable data access and is ideal for storing highly mobile, low-latency data.
