[GitHub] [arrow] jorgecarleitao commented on pull request #8480: ARROW-10327: [Rust] [DataFusion] Replace iterator of batches by iterator of future batch

   * (at least currently) all batches are placed in a single batch before sorting.
   
   * `join_all` [preserves the order](https://docs.rs/futures/0.3.6/futures/future/fn.join_all.html):
   
   > The returned future will drive execution for all of its underlying futures, collecting the results into a destination Vec<T> in the same order as they were provided.
