Join stage partition
Posted: Thu Jul 14, 2011 11:00 am
Hi,
I have a question regarding partition in join stage. My job design is to join two datasets. My question is, should I hash partition during this join in join stage. Because when we join two database stages the join stage will wait till all the records are read form the table and so we will get correct results. Is this the case with joining two datasets too?
Thanks
