• Select the job manager for this node – Select the DataFlow Executor from the list to enable running the workflow in streaming mode using DataFlow run-time environment.
• Settings for selected job manager – Select the execution profile from the Profile list to provide DataFlow engine settings during execution. The profile settings include these for cluster execution.
4. Click OK to complete configuring the workflow to use streaming execution mode.
