摘要： An embodiment of the invention provides a method for exploiting stateless and stateful data parallelism in a streaming application, wherein a compiler determines whether an operator of the streaming application is safe to parallelize based on a definition of the operator and an instance of the definition. The operator is not safe to parallelize when the operator has selectivity greater than 1, wherein the selectivity is the number of output tuples generated for each input tuple. Parallel regions are formed within the streaming application with the compiler when the operator is safe to parallelize. Synchronization strategies for the parallel regions are determined with the compiler, wherein the synchronization strategies are determined based on the definition of the operator and the instance of the definition. The synchronization strategies of the parallel regions are enforced with a runtime system.

摘要： Techniques for composing an application resource model in a data stream processing system are disclosed. The application resource model may be used to understand what resources will be consumed by an application when executed by the data stream processing system. For example, a method for composing an application resource model for a data stream processing system comprises the following steps. One or more operator-level metrics are obtained from an execution of a data stream processing application in accordance with a first configuration. The application is executed by one or more nodes of the data stream processing system, and the application is comprised of one or more processing elements that are comprised of one or more operators. One or more operator-level resource functions are generated based on the obtained one or more operator-level metrics. A processing element-level resource function is generated based on the one or more generated operator-level resource functions. The processing element-level resource function represents an application resource model usable for predicting one or more characteristics of the application executed in accordance with a second configuration.
