I'm getting the same (I believe) error on files with many columns (>2k), and FWIW, can be work'd-around by a `struct ArcFile(Arc<File>)`. Just `impl parquet::file::reader::ChunkReader for ArcFile`, using `FileExt::read_at` on `cfg(unix)` and `FileExt::seek_read` on `cfg(windows)`. I guess we can modify `parquet::util::io::FileSource` to use `Arc<File>`, because we take ownership of provided file objects anyway. -- This is an automated message from the Apache Git Service.
