   Tested this just now with updated code:
   
   ```rust
   #[tokio::test]
   async fn test() -> Result<()> {
       let ctx = SessionContext::new();
       ctx.register_parquet("example", "/home/andy/Downloads/blogs.parquet", ParquetReadOptions::default()).await?;
       let df = ctx.sql("SELECT reply FROM example GROUP BY reply LIMIT 100").await?;
       let record_batches = df.collect().await?;
       println!("sdasd {:?}", record_batches);
       Ok(())
   }
   ```
   
   fails with:
   
   ```
   Error: ArrowError(ExternalError(Execution("Arrow error: External error: Internal error: Unsupported data type in hasher: Struct([Field { name: \"reply_id\", data_type: Int32, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: None }, Field { name: \"next_id\", data_type: Int32, nullable: true, dict_id: 0, dict_is_ordered: false, metadata: None }]). This was likely caused by a bug in DataFusion's code and we would welcome that you file an bug report in our issue tracker")))
