Is Database.Persistent lazy wrt reading fields? I need to iterate over entities containing both small and large fields. I do not need to use the large fields in this instance, and so would rather they were not read from the database.

IIRC, they are read strictly.  I guess you should put them on a different entity.

That's correct. In fact, Persistent avoids any form of lazy I/O to ensure that database connections are returned to the pool as soon as possible (amongst other reasons). Michael
