A technique implements a dataflow graph, taking a number of streams of data inputs and transforms these inputs into a number of streams of outputs. The dataflow graph can perform pattern matching. The technique implements reactions via the composition of pattern matching across joined streams of input data. A completeness of matching an input sequence to a particular input pattern can be characterized as having at least three different degrees, such as cold (not yet matched), warm (e.g., minimally matched), and hot (e.g., maximally matched). The input pattern to be matched can have a variable length, including zero length or unlimited or arbitrarily large length. Data flows can be on a push basis or pull basis, or a combination, and may change depending on the state.
