> Currently there does not exist an interface that allows you to pull a single object at
a time.
> For example when generating a large tabular report loading 500k records into a collection
is memory intensive operation. I would suggest an api that either mirrors the iterator api
of a ResultSet or a callback mechanism so I can process each object once it is created.
> If I have the ability to process a record and throw it away I can generate large reports
without having to be concerned with out of memory errors.
