I’m not talking about obvious cases like static assets.

I mean backend/API work where a cache can help, but also adds invalidation questions, stale data edge cases, and more moving parts. I’ve seen teams add Redis very early and others avoid it until they absolutely have to.

What signals make you say “okay, now caching is justified”?
