cache eviction policies and microservices

Hey everyone, I'm trying to figure out cache eviction in a microservices system. We have multiple services using the same Redis instance for caching shared data. If one service removes a specific key, how do the others find out that key is no longer good? What are the usual ways and best approaches for dealing with distributed cache invalidation between microservices, especially when eviction is the cause, and not just a direct delete? I'd love to hear what you all have tried.
