---------------------------------------

             Summary: [C++] Aggregate nodes don't filter
                 Key: ARROW-13498
                 URL: https://issues.apache.org/jira/browse/ARROW-13498
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: Neal Richardson
             Fix For: 6.0.0


Lots of variations of this fail, both scalar and grouped agg. It's really obvious when you filter on the group-by column and then you see those groups appear, but it seems to be generally true of all filters.

{code}
Table$create(
  group=c(1, 2), 
  value=c(5, 6)
) %>% 
  filter(value > 5) %>% 
  group_by(group) %>% 
  summarize(sum(value)) %>% 
  collect()

# A tibble: 2 x 2
  group `sum(value)`
  <dbl>        <dbl>
1     1            5
2     2            6
{code}
