When it comes to cache invalidation, I've got a few go-to strategies. What about you?

Hey everyone, I've been mulling over cache invalidation quite a bit lately. It really seems like the most difficult part. We've tinkered with a few methods, like using TTL (time-to-live) for expiration, but honestly, that sometimes still means we're showing slightly old information. We've also explored event-driven invalidation, but getting that set up adds a whole layer of complexity. So, what are your go-to methods for handling cache invalidation? Are there specific patterns you tend to rely on, and what are the pros and cons of each?
