Michal Nowakiewicz updated ARROW-13643:
---------------------------------------
Priority: Minor (was: Major)
> [C++][Compute] Implement outer join with support for residual predicates
> ------------------------------------------------------------------------
>
> Key: ARROW-13643
> URL: https://issues.apache.org/jira/browse/ARROW-13643
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Affects Versions: 6.0.0
> Reporter: Michal Nowakiewicz
> Assignee: Michal Nowakiewicz
> Priority: Minor
> Labels: query-engine
> Fix For: 6.0.0
>
>
> Residual predicates are evaluated after finding matches using equality
> condition on key columns, but before deciding whether an input had a match
> for the join and resolving outer references. They allow to implement in a
> simple (but potentially inefficient) way inequality predicates that accompany
> equality predicates in join condition.
