Unique Rows
Description
Unique rows, is a step in the Transformation Plugin for Process Studio Workflows. The Unique rows step passes unique rows by removing duplicate rows from the input stream(s). It is a prerequisite that input stream is sorted; otherwise, only consecutive double rows are evaluated correctly. Unique rows (HashSet) step does not need the rows to be sorted.
