Thanks, @jasonhughes248! This looks like an improvement. I can share the original drawing with you if you want to edit that instead. There are also a couple of things we may want to change. First, I just gave a talk with what I think might be a better series of diagrams than the one here. I'd be interested in getting your feedback on that and whether we should replace the doc based on the new ones instead. [Iceberg Row-level Updates.pdf](https://github.com/apache/iceberg/files/6528986/Iceberg.Row-level.Updates.pdf) Second, assuming that we go with the older drawing, I think we also need to show that both snapshots, `s1` and `s2` exist in the same metadata file. One of the biggest misconceptions is that each metadata file points to a single snapshot, but they actually contain a list of all valid snapshots. Aging off snapshots removes older ones from that list and updates the history, then writes a new metadata file. -- This is an automated message from the Apache Git Service.
