[GitHub] [arrow-rs] jhorstmann commented on issue #1489: Add SIMD support for the `length` kernel

   The compiler should be able to autovectorize the existing length kernel, at least it does in a smaller example: https://rust.godbolt.org/z/7sjrrfxqf
   
   If this does not happen in the actual arrow kernel then we probably need to investigate whether `MutableBuffer::from_trusted_len_iter` somehow prevents that optimization.
