Hi,
in the spec, in §12.7.2 it reads
"Recursive fetch group references are controlled by the fetch-depth
attribute. A fetch-depth of 0 will fetch the whole graph of
instances reachable from this field. The default is 1, meaning that
only the instance directly reachable from this field is fetched."
For a fetch-depth of 1, when we fetch such a reachable instance, what
fields of that instance should be fetched exactly? All I know is we must
not fetch any of its object fields, as recursion stops here. One
solution would be to fetch only the primary key, would that be in the
sense of the specification? It might seem strange, but for my
application this makes the most sense.
Regards,
Jörg
