2. The apparatus of claim 1 , comprising a user interface (UI) component for execution by the processor component to generate, by circuitry for presentation on a display, a selection of tasks and a selection of operations to perform on at least a portion of the source data set, wherein: the selection of tasks comprises the specified task; and the instruction generator is to receive an indication of selection of one or more operations from the presented selection of operations, and to identify at least the first and second subtasks from the selected one or more operations.
3. The apparatus of claim 2 , wherein: the UI component is to generate, by circuitry for presentation on the display, an indication of the determination of whether to perform the first and second subtasks sequentially or at least partly in parallel as a default selection with an option to override the determination; and the instruction generator is to receive an indication of whether the determination is overridden.
