> Key: TAJO-1525
> URL: https://issues.apache.org/jira/browse/TAJO-1525
> Project: Tajo
> Issue Type: Sub-task
> Reporter: Keuntae Park
> Assignee: Keuntae Park
> Fix For: 0.11.0
>
>
> As discussed in TAJO-1517,
> INTERSECT ALL needs new physical operator,
> which returns the exact number of overlapping rows between results of two
> query blocks.
> For example, when query1 returns
> {code}
> 1, 3, 3, 3
> {code}
> while query2 returns
> {code}
> 3, 3
> {code}
> query1 INTERSECT ALL query2 should return
> {code}
> 3, 3
> {code}
> INTERSECT can be implemented by selecting distinct result of above physical
> operator.
