Interesting @acking-you, do you have some code/branch you could share?
I wonder if you tried out using `RowConverter::append` (e.g. clear + append)
https://docs.rs/arrow-row/latest/arrow_row/struct.RowConverter.html#method.append
rather than `convert_columns`? This approach is used in other areas to reduce
allocations.
