> 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.
