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.
