A lot of times when a UUID is used, it's not generated in the db, such as when you need to generate guaranteed unique IDs client side. Also 4 bytes vs 16 is not "equally well" in terms of performance. Note that the the diagram linked at the root of this thread is encoding uuids as strings which means 32-36 bytes instead of 16. |
