    we can run the job without using the removedublicates stage.
    In the sort stage we have one option that is allow dublicates=false,if you set allow dublicates=true,dublicate records also moves from source to target.

    By using aggregator stage and transformer stage. Use the aggregator stage and group the column. In the transformer stage, use if then else condition and count(column)>1 then duplicates else no duplicates.
