To me this looks like everything should be available after this query.
Nevertheless, Cayenne issues additional queries when I access the
RecipientField and Recipient properties:
Now that's interesting.
If the table contains 22.000 records, the additional queries are executed.
If it contains only 100 records, the additional queries are not
executed, i.e. prefetching works as expected.
Is there some mechanism to limit the size of the object structure built
using a single query, maybe due to memory issues?
A fellow developer just pointed out that the garbage collector has
probably started to remove the objects that were created based on the
first big query, so that additional queries are launched to re-create them.
For the moment I'm using an SQLTemplate returning data records.
