This is all true in general, but possibly not helpful in OP's situation. If you naively try to read all records and then try to process them, then you may indeed see an OutOfMemoryError that using a Java cursor and interleaving fetching and processing would solve (but of course, the essential change is the interleaving, not the cursor object).

@KilianFoth "OutOfMemoryError that using a Java cursor and interleaving fetching and processing" I'm not sure I follow. You can do this in Java without using an explicit cursor. You can set your fetch size to 1 if you like but I wouldn't recommend it. Actually the default of 10 per the link is probably way too low for common use cases.
