The new partnership between QlikTech and Teradata is supported by technology integrations from both QlikView and QV Expressor. On the QlikView side, we announced Direct Discovery http://community.qlik.com/blogs/theqlikviewblog/2012/10/19/self-service-big-data-analysis-with-qlikview-direct-discovery which provides the ability to keep the data in Teradata instead of having to extract everything into QlikView memory. This means that part of the workload will now be handled by Teradata as well via queries submitted by QlikView.
Expressor has native parallel TPT Load, Insert, and Upsert capabilities, and was already a Teradata partner prior to the acquisition.
Hope that helps.
