Redis is an in-memory data structure store optimised for sub-millisecond read and write performance, where data is held primarily in RAM with optional persistence to disk. A traditional relational database stores data durably on disk, supports complex SQL queries, enforces schema constraints, and handles datasets that exceed RAM capacity. Redis is not a replacement for a relational database - it is a high-speed complementary layer for caching, sessions, and real-time operations.
