Abstract

See full text

A first processing element may be initially configured to transmit a first output stream to a second processing element. The second processing element may be initially configured to transmit a second output stream to a third processing element. The tuples of the first and second output streams may have the first and second attributes. It may be determined whether the first attribute is to be first processed at the second processing element (first condition) and whether the second attribute is to be first processed at the third processing element (second condition). When the first and second conditions are met, the first processing element may be reconfigured to transmit a third output stream to the second processing element and a fourth output stream to the third processing element. The third output stream may have only the first attribute. The fourth output stream may have only the second attribute.
