1. A method, comprising:

  • receiving streaming data to be processed by a plurality of processing elements comprising one or more of a plurality of operators;

    establishing an operator graph defining at least one execution path in which a first operator of the plurality of operators is configured to receive data tuples from at least one upstream operator and transmit data tuples to at least one downstream operator;

    processing the received streaming data using the first operator when the first operator is fused to a first processing element of the plurality of processing elements;

    un-fusing the first operator from the first processing element;

    before un-fusing the first operator, processing data within the first processing element using the first operator; and

    transferring the first operator to a second processing element of the plurality of processing elements such that the first operator uses a first underutilized hardware resource to process the received streaming data.
