Hello,
I'm very new to Castor, it reads well and the XML integration looks cool.
But I would be very interesed if anyone could answer the following:-
* How are relationship/foreign keys really handled? Suppose one is using
lazy mode to avoid paging in the entire database. I query and retreive
product 123 into p. In the database p has a productgroup 456, but that has
not been retreived. Now, what does p.getProductGroup() return? Is there a
way to page in rows on demand vs all at the beginning?
* As above, but suppose group 456 had been queried. I now query 123. What
does p.getProductGroup return?
* The documentation in the distribution says "TBD" for this and other
issues, is there any other documentation?
* Updates are automatic on commit. What about the order and the effect on
db constraints? In particular, can the databse have explicit foreign key
constraints declared?
* Are there any better examples than the very simple one in examples/jdo in
the distribution?
* Has anyone done benchmarking vs plain JDBC for doing simple non-cached
operations?
* Can OQL handle Order By?
Thanks,
Anthony
PS. The good oil:-
"The greenish extract of a large tropical plant, castor oil has been used
for many years to ease constipation and induce vomiting. Basically, it's
WD40 for the gastro-intestinal tract.
As any Little Rascals fan knows, castor oil is a notoriously ghastly tasting
liquid. Yahoo! Health recommends chilling castor oil in the fridge and
mixing with cold orange juice before ingesting to make it more palatable.
The mind (and tummy) reels."
