Emmmm as a file format, parquet cannot reordering, it needs to maintain all schema in a file as same. So in parquet standard, it cannot reorder within a file. During library writing to parquet, we don't support reorder now because handling this in parquet writer might be tricky. So I think a `select` as a projection would be convinient, efficient and ok here. -- This is an automated message from the Apache Git Service.
