Abstract: Methods and apparatus, including computer program products, implementing and using techniques for data stream processing in a runtime data processing environment. A stream processing graph that includes several connected operators is received. Source code of the operators is analyzed to identify hints describing whether an operator contains data structures, method parameters or other data that can be applied in a parallelization data processing environment. Performance metrics of the data processing environment within parallel regions is evaluated to determine whether data processing resources can be dynamically scaled up or down. In response to determining that the data processing resources can be dynamically scaled up, one or more operators are split to be processed on two or more parallel processing resources. In response to determining that the data processing resources can be dynamically scaled down, one or more operators are combined to be processed on a single parallel processing resource.
