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 options, while Memcached is simpler and faster for basic key-value storage. Ehcache is often used in Java applications and offers more advanced caching strategies.

Which one should I choose for a web application?

It depends on your specific needs. If you need advanced features and data structures, Redis is a great choice. For simple caching needs, Memcached might be sufficient. If you're working within a Java ecosystem, Ehcache could be the best fit.

What about scalability and performance?

Redis scales well with clustering and can handle high throughput, while Memcached is designed for speed and can also scale horizontally. Ehcache can be used in a distributed mode but may require more configuration.

Are there any downsides to using these libraries?

Yes, Redis can be more complex to set up and manage, especially with persistence. Memcached has limited data types and lacks persistence. Ehcache can be heavy on memory usage if not configured properly.
