using fileset lookup stage or not?
Posted: Fri Feb 26, 2010 6:59 am
I have been using datasets with the lookup stage. But then I read about the fileset lookup stage.
What is the difference between using
one master dataset, and one reference dataset and a lookup stage to join on a key
versus
one master dataset, one fileset lookup stage, and one lookup stage to join on a key.
Is it mainly the size of the data, over 2GB or not?
thanks again.
