Description

Is it possible to specify a time wherein the dataloader can keep a copy of the data, but when the time has elapsed, it will automatically clear the cache?

Or we just need to have an external function (setInterval), which calls the [customDataLoader].clear() or [customDataLoader].clearAll()?

Research direction
This issue requests a TTL (time to live) caching feature for DataLoader. To implement, examine the current caching logic in DataLoader's source, specifically the `DataLoader` class methods like `load`, `prime`, and `clear`. Look for any existing PRs or discussions about cache expiration. Consider adding an option for `maxAge` that automatically clears entries after a set duration.
