Cool stuff. I found it especially interesting how they removed 30% of writes with new logic to compose some timelines of events in other timelines. It's a thought provoking optimization that calls to mind graph partitioning. For example you have 10 people in your organization with various permissions on repos. Some people (CTO let's say) can see every repo while others might only be able to see some repos. Or you might have consultants or open source projects which non-employees contribute to. Then you construct a graph where each node is an contributor that is connected to other contributors by the permissions they have on repos (or are the repos the nodes and the contributor permissions the connections?). Finally you run a graph partitioning algorithm where the number of partitions is the number of unique timelines you have to write for an organization. Thinking about an organization with closer to 500 contributors I can see how this could reduce the number of timelines by 30%.
