So, you've got these microservices that talk a lot, and you're wondering about caching.

im working on a microservices architecture where several services constantly need to exchange small pieces of data, almost like a real-time chat. weve been seeing a lot of network traffic and latency. im thinking about implementing some form of caching between these services, maybe a shared cache or local caches. what are your go-to patterns for caching in highly communicative microservice setups? any pitfalls to watch out for?
