jhorstmann opened a new issue #391: URL: https://github.com/apache/arrow-rs/issues/391
The `keys_array` method is a performance pitfall if used in inner loops like in a group by operation. At the time the method was added, the related `keys` method was returning an iterator, making it difficult to randomly access elements. Since then the code was refactored so that `keys` already returns a reference to an Array, which has much less overhead than the code in `keys_array`. This means the `keys_array` method can be removed and its usages directly replaced with `keys`. This would be a backwards incompatible change. For the stable release branch we can think of marking the method as deprecated and direct users to `keys` instead, which might updates to the next major release then less painful. -- This is an automated message from the Apache Git Service.
