Dongjoon Hyun updated TAJO-1430:
--------------------------------
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.
{code:sql}
tsql -f long_2times.sql
...
(0 rows, 30.641 sec, 0 B selected)
...
(0 rows, 1.707 sec, 0 B selected)
{code}
