It's more for performance that you shouldn't use them as PK's - If you insert a lot you'll get massive fragmentation over time. A sequential Id avoids that and still gives you a unique row. The Guid is purely for an external system to grab onto something that I can tie back to an actual row in the database but the external system does not need to know anything about the backend other than <guid>. |
