Hi! I'm Joe from the Relay team. Good questions! It isn't quite as straightforward as you might expect - the interconnected nature of graph-like data means that strategies that work for HTTP don't necessarily apply. For example, storing per-field expiration times could incur additional memory overhead (you might end up with an object per field instead of per record). Storing per-record expiration times is tricky since the same record can have different fields fetched at different times. And a simple max cache size + LIFO/LRU/etc evication strategy means that the cache might evict a record that is still referenced by a view. This type of TTL/expiration is something that we're continuing to explore.
