Subj:   Re: Secondary Indexes on an Active Data Warehouse
 
From:   Judge, James A

How skewed are your NUSIs? Even if there are 000's or 000,000's unique values, is there one (or a few values) that have many (000,000's) base tables rows with the same value. Secondary index skewing is painful for maintenance processes.
