How union transformation is active ?..

Answer / priyank

As per the definition of the Active transformation, the no
of rows going in should be equal to the no of rows going
out.Besides that the row id of the input rows should be the
same the row id of the out going rows.

Henceforth, union transformation is true for the first
condition where the no of rows entering is same as the no
of rows going out as Union transformation treats rows for
UNION ALL condition. But in the second condition i.e. Row
id,there is no control on the rows which enter the Union
transformation from different sources so the Row id can
change.
