Weston Pace commented on ARROW-17783:
-------------------------------------
Do the compute kernels all have tests to verify that they work correctly on
unaligned buffers? I'm not trying to be stubborn here but I haven't been very
involved in the development of the compute kernels and honestly don't know.
> [C++] Aggregate kernel should not mandate alignment
> ---------------------------------------------------

> Key: ARROW-17783
> URL: https://issues.apache.org/jira/browse/ARROW-17783
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Affects Versions: 6.0.0, 8.0.0
> Reporter: Yifei Yang
> Assignee: Weston Pace
> Priority: Major
> Attachments: flight-alignment-test.zip
>
>
> When using arrow's aggregate kernel with table transferred from arrow flight
> (DoGet), it may crash at arrow::util::CheckAlignment(). However using
> original data it works well, also if I first serialize the transferred table
> into bytes then recreate an arrow table using the bytes, it works well.
> "flight-alignment-test" attached is the minimal test that can produce the
> issue, which basically does "sum(total_revenue) group by l_suppkey" using the
> table from "DoGet()". ("DummyNode" is just used to be the producer of the
> aggregate node as the producer is required to create the aggregate node)
