About this document
Teradata Secondary Indexes PDF by Pindiganti is a document available to read on EtoBox.
Secondary Indexes are a unique feature of Teradata, generally defined to provide faster set selection. The system maintains a separate subtable for each secondary index. USI access is usually a two-AMP operation because a USI typically hashes to a different AMP than the PI for the same row.
