The key here is a singleton sequencer component that stamps the new versions. There was a great article shared here on similar techniques used in trading order books (https://news.ycombinator.com/item?id=46192181).

Agree this is the best solution, I’d rather have a tiny failover period than risk serialization issues. Working with FDB has been such a joy because it’s serializable it takes away an entire class of error to consider, leading to simpler implementation.
