**Which part is this question about** <!-- Is it code base, library api, documentation or some other part? --> parquet's api. **Describe your question** <!-- A clear and concise description of what the question is. --> How to do concurrent read/decoding over columns? The similar code can be found in [polars](https://github.com/pola-rs/polars/blob/ab83c2ad27b82148617af1f00bb26ae809c4aa04/crates/polars-io/src/parquet/read_impl.rs#L166) I found the `build_array_reader` function, but I can't construct a `ParquetField`, which is the input param of this function. **Additional context** <!-- Add any other context about the problem here. --> -- This is an automated message from the Apache Git Service.
