>             Project: Apache Arrow
>          Issue Type: Improvement

>            Reporter: Andy Grove
>            Priority: Major

> SortExec has the following error check at execution time and this could be

> time instead.

>     return Err(DataFusionError::Internal(
>         "SortExec requires a single input partition".to_owned(),
>     ));
> } {code}
