Using UUIDs for primary keys offers many benefits, but there are some downsides to consider. The most widely-used UUIDv4 is fully random, which is ideal for minimizing the risk of collision. However, random IDs as primary keys do not index and sort efficiently, leading to index bloat and performance issues.There are new standards that address this problem by including a UNIX timestamp in the initial bits1: UUID v6 and v7.
