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.
