**Which part is this question about** Documentation and examples about writing Parquet files using the `ColumnReader` API. **Describe your question** I'd like to know if there's a clear reason on the absence of examples regarding writing Parquet files using the `ColumnReader` API, and if not, I'd be glad to provide such examples. **Additional context** When looking for info about how to write Parquet files, the first place we end up is the [`parquet::file`](https://docs.rs/parquet/latest/parquet/file/index.html) page on docs.rs, where sample code omits the part where the actual write is done : ```rs // ... while let Some(mut col_writer) = row_group_writer.next_column().unwrap() { // ... write values to a column writer row_group_writer.close_column(col_writer).unwrap(); } // ... ``` While Parquet writing is obviously more complex than other, row-oriented formats and the API is relatively low-level, more documentation and especially examples with both simple and simply nested structures would benefit people, imho. -- This is an automated message from the Apache Git Service.
