   Thanks @thomas-k-cameron  -- given my reading of https://github.com/apache/arrow-datafusion/issues/5779 it seems like perhaps a more direct solution might be to sort the list of files so they are always processed in the same order
   
   Perhaps somehow figure out how to sort the `objects`  by the [`location`](https://docs.rs/object_store/0.6.1/object_store/struct.ObjectMeta.html#structfield.location) field, for example?
   
   ```rust
           let schemas: Vec<_> = futures::stream::iter(objects)
               .map(|object| fetch_schema(store.as_ref(), object, self.metadata_size_hint))
               .boxed() // Workaround https://github.com/rust-lang/rust/issues/64552
               .buffered(SCHEMA_INFERENCE_CONCURRENCY)
               .try_collect()
               .await?;
   ```
