> 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)
