> In order to support Update/Delete we need to read rowId from AcidInputFormat
> and pass that along through the operator pipeline (built from the WHERE
> clause of the SQL Statement) so that it can be written to the delta file by
> the update/delete (sink) operators.
> The parser will add this column to the projection list to make sure it's
> passed along.
