---------------------------------------

             Summary: csv::Reader doesn't propagate schema metadata to RecordBatches
                 Key: ARROW-11632
                 URL: https://issues.apache.org/jira/browse/ARROW-11632
             Project: Apache Arrow
          Issue Type: Bug
          Components: Rust
    Affects Versions: 4.0.0
            Reporter: Marko Mikulicic


Rust csv::Reader doesn't propagate schema metadata to RecordBatches it creates:

 
{code:java}
let reader = csv::ReaderBuilder::new()
    .with_schema(Arc::new(Schema::new_with_metadata(fields, metadata)))
    .build(file)
    .unwrap();

let batch = reader.next().unwrap().unwrap();

assert_eq!(reader.schema(), batch.schema());{code}
 

The parquet writer crate complains about the schema non matching with this error:
Record batch schema does not match writer schema
