David Li commented on ARROW-15678:
----------------------------------
Good catch. This is exactly the same problem we ran into before with kernels:
[https://github.com/apache/arrow/blob/6c10a389bbc35b67187930dc0db2a88671e76c2d/cpp/src/arrow/compute/kernels/aggregate_internal.h#L135-L138]
(ARROW-13382). I wonder if we should reconsider the plan of vectorizing
kernels by rebuilding the same source multiple times given this potential
pitfall.
