What are the differences between caching and database storage in Ruby?
Caching is a temporary storage solution that speeds up data retrieval, while databases are for persistent data storage.
When should I use caching instead of querying the database?
Use caching for frequently accessed data that doesn't change often, to reduce database load and improve performance.
Can you give me an example of caching in a Ruby application?
Sure! In a Ruby on Rails app, you can use Rails.cache to store the results of expensive queries.
What are the downsides of using caching?
Downsides include potential stale data, increased complexity, and the need for cache invalidation strategies.
