Subj:   Re: Collect statistics necessary on tables with a unique primary index
From:   Larry Swanson

This topic is well covered in history but here goes nothing:

Generally you want to collect statistics on:

A UPI of a table with less than 1000 rows per AMP.

ALL non-unique indexes.

For a more complete treatment refer to the manuals and/or TERADATA Users Guide from Coffing.
