> I noticed this while benchmarking improvements in ARROW-9895. A flamegraph
> showed a significant amount of time spent in Arc::clone/atomic_add followed
> by Arc::drop/atomic_sub
> The Array trait has two methods for accessing ArrayData, `.data()` which
> clones an `Arc<ArrayData>` and `.data_ref()` which only borrows the data. In
> many places borrow can be used instead of clone.
