What's the advantage of Modify stage?
Posted: Sat Aug 22, 2009 12:09 pm
Hello all,
I was wondering why one should use modify stage when other stages can be used instead of modify stage?
As per my understanding renaming columns, dropping columns, changing datatype can be achieved using Copy stage instead of Modify Stage.
I know Modify stage performs better since it's a primitive stage. What are the other advantages of Modify stage over others?
Thanks for your time.
