Subj:   Re: Couting duplicate rows thru multi load
From:   Dwight Etheridge

My experience has been that the writing of that UV table may be performed on a row-by-row basis, not in a block fashion. So it may be slow.

Why not multiload the 25 million to a multiset staging table. Then use SQL and grouping to find the duplicates and non-duplicates. At least you stay with parallel operations.
