James Taylor updated PHOENIX-2270:
----------------------------------
Description: Phoenix should have a physical operator that executes a sort
on the server-side which Drill can leverage when re-ordering is necessary.
Unlike PHOENIX-2269 which is clearing going to be more efficient to let Phoenix
handle, the sort is more of a gray area. Phoenix will be faster in the way it
does the scan within the coprocessor, but it still needs to return the same
number of rows. This process puts a pretty heavy burden on the region server as
well. We should measure performance with and without Phoenix doing the sort.
