Abstract: A stream of tuples may be processed by receiving at a first stream operator a first tuple from a stream of tuples. In response to receiving the first tuple, port mutability conditions for a first stream operator and a second stream operator may be analyzed. In response to identifying the port mutability conditions for a first stream operator and a second stream operator, a first set of attribute mutability conditions for the first tuple received at the first stream operator may be identified. Based on the first set of attribute mutability conditions, a reference of an attribute from the first tuple may be generated where the reference is added to a second tuple passing from the first stream operator to the second stream operator.

Abstract: A pedigree data processing system receives a first item from an upstream partner and generates a receive native event for the first item. The mechanism receives pedigree data for the first item from the upstream partner, generates at least one synthetic event based on the pedigree data and stores the receive native event and the at least one synthetic event in a pedigree data repository. The pedigree data processing system determines whether to send electronic pedigree information for the first item to downstream partners using push data exchange or pull data exchange. The pedigree data processing system generates an electronic pedigree for the first item using pull data exchange based on the receive native event and the at least one synthetic event and provides the electronic pedigree to a first downstream partner pedigree system.

Abstract: A selective predictor utilizes a selective prediction method for coordinate data encoding. The selective predictor may calculate multiple prediction vectors for each vertex in the shape traversal order. Then, the selective predictor selects the vector that is closest to the vertex to be estimated. In determining the multiple prediction vectors, the selective predictor considers the position of several previous vertices in the traversal order. The selective predictor outputs a correction vector for the selected prediction vector and identification information indicting the selected prediction vector.
