Hitesh Sanjay Nalamwar it's usually best to go for an immediate cache refresh. However, to minimize the performance hit, you could combine immediate invalidation with a lightweight refresh strategy. For example, you could invalidate the cache immediately but fetch the updated data asynchronously in the background. This way, users still get the most up-to-date information, but the performance impact is minimized.

I always appreciate the clear breakdown of latency optimization strategies. One question—when implementing caching at scale, especially server-side with tools like Redis, how do you recommend handling cache invalidation to ensure data freshness without hurting performance?
