What does the Multicast transformation do?
The Multicast creates as many copies of the entire data flow as you want. There is very little configuration available – all you can do is add a Name and Description for each output once you have created it by dragging one to a transformation or destination.
1)The main use is where you need to perform different operations on the same set of data.
2)Another use i’ve had was directing slightly different versions same set of source data to different file locations.
