      Description

      There are wide tables with many many columns. Moveover, BI tools generate very complex queries whose size is several MB. Although Tajo executes those queries very fast in a few seconds, the total time of UX is slow.
      To become a fastest Hadoop DW, we need this following feature.

      tsql -f long_2times.sql
      ...
      (0 rows, 30.641 sec, 0 B selected)
      ...
      (0 rows, 1.707 sec, 0 B selected)
