User Guide

The QueryGridâ„¢ feature in Teradata provides a way to read data from or write data to a remote database host. Packages are available as add-ons to the Teradata RDBMS for several varieties of foreign host, including Teradata, Aster, Oracle and several variations of Hadoop.

In order to use the QueryGrid features for a particular host type within Teradata Warehouse Miner, the underlying QueryGrid package must have been purchased and installed within Teradata, and Teradata Warehouse Miner must have been certified with that particular package (as documented in the Teradata Warehouse Miner Release Definition, B035-2494). Although a QueryGrid package may have some unique features for a particular host type, the same basic user interface is provided for each host type.
