What are the differences between popular caching libraries?

There are several popular caching libraries like Redis, Memcached, and Ehcache. Redis is known for its rich data types and persistence, while Memcached is simpler and faster for basic key-value storage. Ehcache is often used in Java applications and offers features like disk storage.

Which one should I choose for a web application?

It depends on your specific needs. If you need advanced data structures and persistence, Redis is a great choice. For simple caching needs with high performance, Memcached is suitable. If you're working with Java, Ehcache might be the best fit.

Can you explain the performance differences?

Redis generally offers better performance for complex queries due to its in-memory data structure, while Memcached is optimized for speed with simple key-value pairs. However, the actual performance can vary based on your use case and data access patterns.

What about scalability?

Redis supports clustering and partitioning, making it highly scalable. Memcached can also be scaled horizontally by adding more nodes, but it doesn't support data persistence, which can be a limitation for some applications.
