------------------------------------
I see. Ok, maybe we can't do this at planning time then.
> [Rust] [DataFusion] Move SortExec partition check to constructor
> ----------------------------------------------------------------
>
> Key: ARROW-11625
> URL: https://issues.apache.org/jira/browse/ARROW-11625
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Rust - DataFusion
> Reporter: Andy Grove
> Priority: Major
> Fix For: 4.0.0
>
>
> SortExec has the following error check at execution time and this could be
> moved into the try_new constructor so the error check happens at planning
> time instead.
>
> {code:java}
> if 1 != self.input.output_partitioning().partition_count() {
> return Err(DataFusionError::Internal(
> "SortExec requires a single input partition".to_owned(),
> ));
> } {code}
