Redis vs MongoDB: Which is better for your project?

What are the main differences between Redis and MongoDB?

Redis is an in-memory data structure store, while MongoDB is a NoSQL database. Redis is faster for caching, while MongoDB is better for complex queries.

When should I use Redis instead of MongoDB?

Use Redis when you need high-speed data access, like caching or real-time analytics. MongoDB is better for storing large amounts of structured data.

Can I use both Redis and MongoDB together?

Yes, many applications use both. Redis can handle caching and session management, while MongoDB stores the main data.

What are the performance implications of using one over the other?

Redis generally offers lower latency and higher throughput due to its in-memory nature, while MongoDB can handle larger datasets but may have higher latency.
