                 Key: ARROW-16630
                 URL: https://issues.apache.org/jira/browse/ARROW-16630

          Issue Type: Improvement
          Components: C++

BottomK is implemented as TopK on reverse-sorted data. You get the rows you wanted, but the problem is that they're in reversed order.
