Redis

Redis vs MongoDB: when should each be used for data storage?

The question is about Redis .

Answer:
Redis is the ideal choice for temporary, high-speed data access-such as caching, session storage, rate limiting, leaderboards, and real-time pub/sub-where sub-millisecond latency is essential. MongoDB is the suitable option for durable, flexible document storage where data must persist through restarts, support complex queries, and scale beyond RAM capacity. The two technologies complement each other-Redis as the rapid access layer and MongoDB as the main persistent document store.
