Daniël Heres updated ARROW-10892:

>                 Key: ARROW-10892
>                 URL: https://issues.apache.org/jira/browse/ARROW-10892
>             Project: Apache Arrow
>          Issue Type: Bug
>            Reporter: Daniël Heres
>            Priority: Minor
>
> The value functions in the primitive / string / etc arrays are often used to get elements at i in a loop.  Some of them don't have boundary checks for performance reasons, so usage of them is unsafe.
> We should introduce a safe iterator that doesn't do boundary checks and can be used to iterate over the elements of the array. Maybe values_iter would be a good name?
