Managing passthru connections on an operator graph

A computer program product for processing a stream of tuples, each tuple containing one or more attributes, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code comprising computer readable program code configured to:

• process the attributes of the stream of tuples using stream operators operating on one or more computer processors and corresponding one or more processing elements;
• detect an indicative element from a plurality of stream operators;
• transmit, in response to detecting the indicative element, a passthru command to a processing element corresponding to the indicative element, wherein the transmit the passthru command includes:
• determine a performance factor of the passthru command on the processing element,
• determine a threshold based on resources of a computing system, and
• select, in response to the performance factor falling within the threshold, the passthru command;
• and
• alter, in response to receiving the passthru command at the processing element, a portion of attribute processing for the indicative element.
