What are the differences between Redis and Memcached for Rails caching?

Redis and Memcached are both in-memory data stores used for caching in Rails, but they have key differences. Redis supports data persistence, complex data types, and built-in replication, while Memcached is simpler and focuses on speed and simplicity.

Which one should I choose for my Rails application?

It depends on your needs. If you require advanced data structures or persistence, go with Redis. If you need a straightforward caching solution with high performance, Memcached might be better.

Can I use both in the same application?

Yes, you can use both in the same application. For example, you might use Redis for session storage and Memcached for caching database queries.

What are some best practices for using Redis in Rails?

Some best practices include using Redis for caching frequently accessed data, setting appropriate expiration times, and monitoring performance to avoid memory issues.
