I understand that a SET table has an overhead of checking for duplicate rows while data is being inserted into the table. However, if the table has a UPI/USI defined on it, only the UPI/USI columns are checked for duplicates and not duplicate row checks. Is this understanding correct ?

Hey guys, When you have a NUPI, it's good to have a USI because this can enforce uniqueness on your NUPI. Just wanted to ask for a particular scenario where you will have a combination of NUPI and USI?
