1. A method for recommending streams application actors for fusion, wherein the streams application actors are dispersed on an operator graph within a streaming environment, the method comprising: generating, for each of two or more streams application actors in the operator graph, a streams application actor profile; determining, from streams application actor profiles for two or more streams application actors, the two or more streams application actors are fusion candidates, wherein the determining is based on streams application actor profile data, including historical runtime data and real-time processing data, and based on the streams application actors satisfying at least one fusion candidate rule from a set of fusion candidate rules, each fusion candidate rule associated with one or more fusion recommendations, wherein the fusion recommendation includes reconfiguration data for a particular portion of the operator graph; identifying, in response to the determining, a fusion recommendation, from the one or more fusion recommendations associated with the at least one fusion candidate rule; and displaying, in response to the identifying, an identity of each of the two or more streams application actors and the fusion recommendation.
