    Default sort rows and unique

    I'm trying to use a Sort rows step to only keep unique rows. It works fine until I change the number of copies to start, say 2. In that scenario, my duplicate rows all pass through it. Is this a bug or a feature limitation? I'm guessing it has to do with distributing the rows to the number of copies you specify.

    Have a look at the http://wiki.pentaho.com/display/EAI/Sorted+Merge
    I just added the use case to the doc and put a note on the Sort rows step about your use case.

    HTH,
