      Description

      Rowkey is led by date non null.

      explain select max(date) from foobar where date < to_date('2013-02-17 00:00:00')

      [["PLAN"],
      ["CLIENT PARALLEL 7-WAY RANGE SCAN OVER FOOBAR TO (2013-02-17 00:00:00) EXCLUSIVE"],
      [" SERVER FILTER BY FirstKeyOnlyFilter"],
      [" SERVER AGGREGATE INTO SINGLE ROW"]]

      Does this plan imply we scan from the beginning of the table up to the specified endpoint?
