A union transformation is a multiple input group
transformation,which is used to merge the data from multiple
sources similar to UNION All SQL statements to combine the
results from 2 or more sql statements.
Similar to UNION All statement, the union transformation
doesn't remove duplicate rows.

It is an active transformation.
