What happens if you need to catch up? You keep calling in a loop with a new lastEventId?

What is the intention there though. Is this for social media type feeds, or is this meant for synchronising data (at the extreme for DB replication for example!).

What if anything is expected of the producer in terms of how long to store events?

Sounds like it. But the compaction section has more details - basically you can discard events that are overwritten by later ones
