How do I implement cache expiration in my application?

To implement cache expiration, you can set a time-to-live (TTL) for your cached items. This defines how long they should be stored before being considered stale.

What are the common strategies for cache expiration?

Common strategies include time-based expiration, where items expire after a set time, and event-based expiration, where items are invalidated based on specific events.

Can you give me an example of time-based expiration?

Sure! For instance, if you cache user profile data, you might set a TTL of 10 minutes. After 10 minutes, the data is removed from the cache.

How can I monitor cache performance?

You can monitor cache performance by tracking hit rates, miss rates, and the average time items spend in the cache. Tools like Redis or Memcached provide built-in metrics.
