1. A method for generating a synthetic workload for stream computing, wherein the method comprises: generating an undirected graph that meets a node degree distribution parameter; obtaining a user-defined parameter for at least one feature for at least one stream computing application; and manipulating the undirected graph to generate a synthetic workload for stream computing in compliance with the user-defined parameter for the at least one feature for the at least one stream computing application; wherein at least one of the steps is carried out by a computer device.
