Answer Posted / rakesh gupta
There is not much difference between cdc stage and difference stage.Both the stage similar.
Difference between cdc stage and difference are following:-
1.In CDC stage,we should have same number of columns and same column name from both the input link.However,In difference stage we can have different number of column and Different column name.
2.The CDC stage takes two input data sets, denoted before and after, and outputs a single data set whose records represent the changes made to the before data set to obtain the after data set.However,Difference stage performs a record-by-record comparison of two input data sets, which are different versions of the same data set designated the before and after data sets. The Difference stage outputs a single data set whose records represent the difference between them.
