How can I handle cache invalidations in Flask?

In Flask, you can handle cache invalidations by using the Flask-Caching extension. You can set up cache keys and use methods like cache.delete() to invalidate specific entries.

Can you give me an example of how to implement that?

Sure! First, install Flask-Caching. Then, you can use the @cache.cached() decorator for your routes. To invalidate, call cache.delete('your_cache_key') when the data changes.

What if I want to invalidate all cache entries?

You can use cache.clear() to remove all cached entries. Just be cautious, as this will clear everything!

Are there any performance considerations I should be aware of?

Yes, frequent cache invalidations can lead to performance hits. It's best to strike a balance between cache freshness and performance.
