1. A method for processing data, comprising:

  • receiving streaming data tuples to be processed by a plurality of operators, the operators processing at least a portion of the received data tuples by operation of one or more computer processors;

    establishing an operator graph of the plurality of operators, the 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;

    measuring a current rate at which data tuples pass from the upstream operator to the first operator during a period of time; and

    triggering a data window in at least one operator of the plurality of operators based on the current rate, the window comprising a set of data tuples to be processed by the at least one operator.
