[I] df.write_xxx no longer working in ballista [arrow-ballista]

["yarenty (via GitHub)" <gi...@apache.org>]

yarenty opened a new issue, #894:
URL: https://github.com/apache/arrow-ballista/issues/894

   **Describe the bug**
   
   Since the update to Datafusion 30 ( rev: 7d774481aedc027b7f68226b2c3a4fc0db959fc2 )
   as Dataframe moved to use LogicalPlan::Copy when executing write (csv, parquet,json)
   df. write_xxx is no longer working in Ballista.
   
   
   **To Reproduce**
   One can use any sql and then df.write ie: in examples standalone_sql.rs add write_csv() instead show():
   
   ``` 
       let df = ctx.sql("select count(1) from test").await?;
   
       df.write_csv("output.csv", DataFrameWriteOptions::default(), None).await?;
   ```
   
   
   `cargo run --example standalone_sql`
   
   Output: 
   ```
   Error: DataFusionError(Internal("failed to serialize logical plan: Internal(\"LogicalPlan serde is not yet implemented for Copy\")"))
   ```
   
   **Expected behavior**
   File created.
   
   
   **Additional context**
   See PR:  https://github.com/apache/arrow-datafusion/pull/7283
   
   Looks like this is todo -  there are no serde / proto changes in datafusion. 
   
   *Question: should I ask about it in datafusion repo ?*
