What Are the Most Efficient Techniques for Data Retrieval in Large Databases?

Hey! Data retrieval can be tricky, but one thing that’s helped me is using *database replication*. It spreads the load across multiple servers, so you’re not bottlenecking one.

For caching, *NGINX* is a solid choice. It’s lightweight and super fast.

Also, if you’re working with JSON data, *MongoDB* is worth a look. It’s not SQL, but it’s great for unstructured data.
