Vantage comes with QueryGrid configured and ready to work with Machine Learning Engine. When QueryGrid is deployed on a Vantage system, QueryGrid links are automatically created between Advanced SQL Engine and Machine Learning Engine communication. The default foreign server name for Machine Learning Engine is td_server_db.coprocessor.
If you have an existing QueryGrid environment, Vantage
QueryGrid must be clustered with your existing QueryGrid Manager to enable Advanced SQL Engine to communicate with all the existing QueryGrid-connected databases.
The option to cluster an external QueryGrid environment with Vantage
QueryGrid must be determined at the time of purchase. Clustering is done by Teradata Customer Support as part of the Vantage installation.
Contact Teradata Professional Services to merge an external QueryGrid cluster to Vantage
QueryGrid if all of the following are true:- You have a QueryGrid environment outside of Vantage.
- Your external QueryGrid environment is running QueryGrid version 02.08.00.02 or later.
- The external QueryGrid Manager was not clustered with Vantage QueryGrid during installation.
