    Description

      Currently we disallow queries if the partition specifications of all Wdw fns are not the same. We can relax this by generating multiple PTFOps based on the unique partitionings in a Query. For partitionings that only differ in sort, we can introduce a sort step in between PTFOps, which can happen in the same Reduce task.
