How do I implement cache invalidation in my application?

Cache invalidation is crucial for ensuring that your application serves up-to-date data. There are several strategies you can use, such as time-based expiration, event-based invalidation, or manual invalidation. Which approach are you considering?

I'm thinking about using event-based invalidation. Can you explain how that works?

Sure! Event-based invalidation involves listening for specific events in your application that indicate data changes. When an event occurs, you can invalidate the cache for the affected data. This ensures that users always receive the most current information. Do you have a specific event in mind?

Yes, I want to invalidate the cache when a user updates their profile. How would I set that up?

You can set up a listener for the profile update event. When the event is triggered, you would call a function to remove the cached profile data for that user. This can be done using a cache library that supports invalidation. Would you like a code example?

Yes, that would be great!
