Skip workload mapping when there is no workload #355

Closed yangdsh closed 4 years ago

yangdsh commented 4 years ago

Tricky thing: we need the mapped workload data. It is merged with the target data for further processing.

Solution: when we skip workload mapping, I assign the target data to the mapped workload data. So essentially the target data is merged with itself, and the duplicate rows are removed, which means the target data remains the same after merging. However, we cannot do knob ranking without workload data.
