Answer 1

This is the classic problem of caching – cash refresh and expiry. The answer is that it depends on how much of an issue it is have stale data. If it’s critical not to then don’t cache. Otherwise you can update the cache by having a trigger (for example in the db or the db writer) that raises and event that a listener will catch an issue a refresh asynchronously.
