dont have many ideas for caching strategies for data that gets read a lot, but isnt written to very often.

hey everyone, i'm working on a system that has a lot of read operations for data that doesn't change too often. we're seeing some performance bottlenecks and i'm thinking caching is the way to go. what are your favorite caching strategies for read-heavy scenarios? i've been looking into things like Redis and Memcached, but i'm also wondering about in-memory caching within the application itself. what trade-offs did you encounter when choosing between different approaches? curious to hear your experiences
