This question is a real head-scratcher. I'm just hoping I don't end up 'caching' my career if I get it wrong!

I think option A sounds like the best approach to minimize redundant transactions and keep the data fresh.

C) Use a Scheduler with a fixed frequency set to every hour to trigger an invalidate cache flow. Use an object-store-caching-strategy and the default expiration interval.

A) Use an On Table Row operation configured with the Employees table, call invalidate cache, and hardcode the new Employees data to cache. Use an object-store-caching-strategy and set the expiration interval to 1 hour.

Hmm, this question is a real brain-teaser. I'm going to go with option D - it seems the most robust and reliable solution.

C is a nice compromise, but I'd rather not rely on a scheduled job to invalidate the cache. Seems like a potential point of failure.

A is a bit overkill, don't you think? Hardcoding the data feels like a hack, and 1 hour is too long for a cache expiration.

D is the best choice here. Scheduled invalidation with a 1-hour expiration interval ensures the cache is up-to-date without unnecessary database queries.

Option B seems like the way to go. Keep it simple and let the default expiration interval handle the caching.
