When will a data page with customer data be reloaded if it is configured to become stale after one hour?

A data page configured to become stale after one hour will reload on the next access one hour after it was last accessed. This means that once the data page surpasses the specified time limit of one hour since it was last retrieved, it does not immediately reload at that one-hour mark. Instead, it is refreshed the next time a request is made for that data page. This approach enhances performance by preventing unnecessary reloads when data is still valid and can be reused, ensuring that system resources are used efficiently.

The other options do not accurately reflect how data pages operate in this context. For instance, the idea that the data page reloads automatically one hour after it was last accessed misrepresents the mechanism—reloads only occur with subsequent requests. Similarly, associating the reload with the moment of creation rather than the last access does not align with how data page staleness is determined.
