on this question: For the query corresponding to the table with denormalized schema, what do you notice? The results were the same All benchmark field values were decreased close The Bytes shuffled, Slot time consumed, and Bytes spilled to disk increased check The Elapsed time and Slot time consumed decreased None of these answers matched my actual results. The denormalized query took 9 seconds of slot time and the normalized one took 8. You should make sure your data consistently illustrates the point that you want it to illustrate.
