    2525Implementing an auto-increment field in SimpleDB would be extremely difficult.  I would say impossible, actually.  The eventual consistency model just doesn't support it.  For the persistence layers I have written on top of SimpleDB, I use a UUID (type 4) as the ID of the object.  --garnaat

     27Conclusion: Portable code should never assume that the "pk" field is a number. If an entity uses a string pk the application should continue to work.
