[GitHub] [arrow-rs] tustvold commented on pull request #2915: Add `freeze_with_dictionary` API to `MutableArrayData`

   > Just feeling that this way it is somehow not efficient as it needs to freeze and make an array, then takes the value array and copy and attach it back.
   
   I think I am missing something. I don't think there is a way to avoid copying and attaching back - this is what MutableArrayData does also? I did create https://github.com/apache/arrow-rs/issues/1981 a while back to track allowing mutation of arrays, but currently there isn't any support for this?
