I wonder if there is any way (or let’s call it maybe a “best practice”) to create a clean interface to a (wrapped) metanode.
This is my situation: I want to encapsulate a certain functionality into a metanode and share it with other people. However, the functionality of my metanode requires certain data/columns to be present in its input stream. How can I ensure this?
(In object oriented programming this would be an interface definition)
Maybe I am even approaching the problem from the wrong side and there is a different way to do this within ETL tools…? So I would appreciate any comments on this!
Thanks in advance!
