Hi all,
Funnel stage does union operation corresponding to the input and the output link or it does union all operation?
I want to remove duplicates as well, so i have doubt whether i have to use remove duplicates stage or not after that.
Thanks in advance.

Funnel puts all rows from all inputs onto its single output. That's a UNION ALL. There is no capacity within the Funnel stage to remove duplicates. Remember, one task, one stage type.
