since I would expect that the driver retrieves the result sets in chunks I'd
like to know if this behaviour can be controlled - i.e. is setFetchSize()

Actually, at the moment the driver gets all the result set at once, so
no setFetchSize() isn't implemented.

However you can get a cursor back and scroll through the result set
yourself
