Downside: might do the shuffle twice. Upside: shouldn't get incompatible exchanges anymore. Long term we could consider the optimizer rule that I mentioned of "if there are equivalent shuffles in a plan, but one could be native and the other not, consider follow back for the reuse benefit rather than run two different stages to generate the same shuffle data." -- This is an automated message from the Apache Git Service.
