   @houqp This what I'm seeing - and please correct me if I'm wrong - there is no support in reading nested parquet files in DataFusion.
   
   I've tried to use the [`nested_struct.rust.parquet`](https://github.com/apache/parquet-testing/blob/master/data/nested_structs.rust.parquet) file that is present in the `parquet-testing` git submodule for some DataFusion tests and is not working. And I couldn't find any other tests with nested fields in parquet in DataFusion.
   
   With all these being said, what's the strategy on supporting nested source structures in DataFusion?
