extracts and temp files is a valid strategy.
you can also try joblets-- they allow you to pass a schema in and out.
Hi, I've searched the forum in the past and don't think there is currently a way to pass data streams from father to child job for processing. What could be done to avoid reading a large file multiple times in each child job? Is there a way around it? One thing that comes to mind is creating extracts for each child job. Any suggestions? Thanks
