Couchbase vs Redis: which is better for caching + persistence use cases?

Redis is a leading caching solution focused on ultra-fast in-memory storage and simple persistence to disk. It's recommended for projects with heavy cache workloads or temporary data. Couchbase is a full NoSQL database that offers persistent document storage combined with high-performance caching through its built-in memory engine. It's better suited to use cases that require both caching and robust persistent database capabilities in one platform.
