      Description

      For serial query(query with “serial" hint or “limit" without "order by”), we can limit each scan(using page filter) to “limit+offset” instead of limit earlier.
      And then, for all queries, we can forward the relevant client iterators to the offset provided and then return the result.

      syntax

      [ LIMIT { count } ]
          [ OFFSET start [ ROW | ROWS ] ]
          [ FETCH { FIRST | NEXT } [ count ] { ROW | ROWS } ONLY ]
      

      Some new keywords(OFFSET,FETCH,ROW, ROWS,ONLY) are getting introduced so users might need to see that they are not using them as column name or something.

      WDYT, James Taylor
