What are some effective cache invalidation strategies in Django?

In Django, effective cache invalidation strategies include using signals, versioning, and time-based expiration.

Can you explain how to use signals for cache invalidation?

Sure! You can use Django's signals like post_save and post_delete to clear or update the cache when a model instance is saved or deleted.

What is cache versioning and how does it work?

Cache versioning involves assigning a version number to your cache keys. When you update your data, you also increment the version number, effectively invalidating the old cache.

Are there any best practices for setting cache expiration times?

Yes, best practices include setting expiration times based on data volatility, using shorter times for frequently changing data, and longer times for static data.
