Lower bound/Upper bound

TDV uses Explain Plan to arrive at a numeric estimate of the cost of shipping data from a node to the Data Virtualizer. When the cost of shipping a federated query node falls between the limits of the Lowerbound and Upperbound, it is considered eligible for shipment so that it can be processed locally.
