Jefffrey opened a new issue, #5152: URL: https://github.com/apache/arrow-rs/issues/5152
**Describe the bug** <!-- A clear and concise description of what the bug is. --> Column order needs to be written in FileMetadata, see thrift spec: https://github.com/apache/parquet-format/blob/066f9817332da32bdc6dc6dea833b6ee9c269934/src/main/thrift/parquet.thrift#L1133-L1149 **To Reproduce** <!-- Steps to reproduce the behavior: --> In `arrow_writer/mod.rs`: ```rust #[test] fn test_123() { let a = Int32Array::from(vec![1, 2, 3, 4, 5]); let b = IntervalDayTimeArray::from(vec![0; 5]); let batch = RecordBatch::try_from_iter(vec![ ("a", Arc::new(a) as ArrayRef), ("b", Arc::new(b) as ArrayRef), ]) .unwrap(); let mut buf = Vec::with_capacity(1024); let mut writer = ArrowWriter::try_new(&mut buf, batch.schema(), None).unwrap(); writer.write(&batch).unwrap(); writer.close().unwrap(); let bytes = Bytes::from(buf); let options = ReadOptionsBuilder::new().with_page_index().build(); let reader = SerializedFileReader::new_with_options(bytes, options).unwrap(); dbg!(reader.metadata().file_metadata().column_orders()); } ``` Currently outputting `None` **Expected behavior** <!-- A clear and concise description of what you expected to happen. --> Should write ColumnOrder for each column **Additional context** <!-- Add any other context about the problem here. --> See here: https://github.com/apache/arrow-rs/blob/6d4b8bbad95c7e4fec0c4f1fb755ad7a1c542983/parquet/src/file/writer.rs#L326-L336 Currently being set to `None` always when writing -- This is an automated message from the Apache Git Service.
