How do I debug cache-aside pattern issues?

I'm having trouble with the cache-aside pattern in my application. How can I debug it?

Debugging the cache-aside pattern involves checking both the cache and the data source. What specific issues are you facing?

Sometimes the cache returns stale data, and other times it misses the data completely.

For stale data, ensure your cache invalidation strategy is effective. For misses, check if the data is being correctly loaded into the cache.

How can I implement a better cache invalidation strategy?

Consider using time-based expiration or event-based invalidation to keep your cache fresh. Would you like examples of these strategies?
