Is there a way in Cayenne, possibly using Transactions, that we can perform this import, do inserts and queries against the transaction and only commit/rollback at the end?
Subclass the Cayenne context, override performQuery and add in your own custom code there to look for new objects within the context? There is almost certainly a way to have a database transaction cross several Cayenne commits as well, but I can't assist there.
In fact we've done this several times in our application and I was just thinking the other day whether this might be an option in a new generified performQuery and might be useful to be pushed into Cayenne.
