Review Comment:
> So on the contrary I think `exportTable` should be passed the
`arrowSchema` here, since below we import from `consumerArrowSchema`. If we
never export to it, it'll be uninitialized, and I don't know off the top of my
head if the buffer will be zeroed or just contain random bytes, but that could
cause an exception/crash.
Ok. I will look into it over the weekend.
