Some of you may be familiar with relational databases other than Teradata and how those other RDBMs utilize indexes. In Teradata, an âIndexâ is a physical mechanism that is used to distribute, store, and access data rows. Indexes provide a physical access path to the data and their use can avoid unnecessary full-table scans to locate rows.
It is recommended that we should explicitly specify the PRIMARY INDEX for a column in a table since we can assign a proper field for a primary index that will help Teradata to spread the data across the amps efficiently. For a SET table, it is advised to use UNIQUE PRIMARY INDEX since it will not allow duplicate rows.
