Other advantages of UUIDs: - client can generate the UUID, allowing eventual consistency and retrying using distributed DBs (other DB is on phone for example)

Other advantages of UUIDs: - client can generate the UUID, allowing eventual consistency and retrying using distributed DBs (other DB is on phone for example) - merging of DBs is easy - allows capability based access control (you can’t guess the UUID, you don’t have access) - can use a bit or teo to encode production vs development IDs, so cross contamination of systems is less likely
