What are the different cache store options in Ruby on Rails?

In Ruby on Rails, you have several cache store options including MemoryStore, FileStore, MemCacheStore, and RedisCacheStore. Each has its own use cases and performance characteristics.

Can you explain the differences between MemoryStore and RedisCacheStore?

Sure! MemoryStore keeps all cached data in memory, making it very fast but not suitable for large datasets or distributed applications. RedisCacheStore, on the other hand, uses Redis as a backend, allowing for persistence and scalability across multiple servers.

When should I use FileStore?

FileStore is useful for caching data that doesn't change often and can be stored on disk. It's a good option for development or small applications but may not perform well under heavy load.

What are the performance implications of using MemCacheStore?

MemCacheStore is designed for high-performance caching and is great for read-heavy applications. However, it requires a separate Memcached server and can lose data if the server goes down.
