v4 vs v7 vs v1 — which should I use?
v4 is fully random — use it by default. v7 embeds a millisecond timestamp so IDs sort chronologically, which makes them better as database primary keys (better index locality than random v4). v1 also encodes a timestamp but includes a MAC-address-derived field, which v7 avoids.
