[GitHub] [arrow-rs] HaoYang670 opened a new issue #1470: Add `length` kernel support for `ListArray`

HaoYang670 opened a new issue #1470:
URL: https://github.com/apache/arrow-rs/issues/1470


   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   Currently, the `length` kernel only works with `StringArray`. It is reasonable to make it support the `ListArray`.
   
   **Describe the solution you'd like**
   it should be possible to call something like `arrow::compute::length(list_array)` and return an array that contains the length of all lists.
