Hi Mark, I haven’t done any benchmarking comparing Flakes to UUIDs. However the primary benefit of flake IDs, over a traditional UUID, e.g. UUID-1, is flakes do not require coordination (i.e. to avoid clock-skew and duplicate IDs), provide k-ordering (UUID-1’s bit ordering breaks this), and use the standard Unix epoch. It would be interesting to compare performance, but the features of flakes are certainly their primary selling points.
