   working version of code:
   
   ```
   use datafusion::prelude::*;
   
   #[tokio::main]
   async fn main() -> datafusion::error::Result<()> {
       let ctx: SessionContext = SessionContext::new();
       let raw_covid_path: &str = "/mnt/bigdata/covid/owid-covid-data.csv";
       let stage_covid_path = "/tmp/covid";
       let covid_df = ctx.read_csv(raw_covid_path,
                                   CsvReadOptions::new()).await?;
       covid_df.write_parquet(stage_covid_path,None).await?;
       Ok(())
   }
   ```
   
   confirmed that this produces a 4 byte parquet file
