| | We have a 8 node teradata system ,each node having 20 AMPS. Can someone explain me how Bynet determines the node on which table is stored
or to which node the query has to be sent? | |
The following article explains how queries are dispatched to a particular node:
www.teradataforum.com/teradata/20030714_221004.htm .
The dispatching algorithm does not use information on how tables are stored. That would be the task for the optimizer.

Victor
