Another interesting API question: How do we represent the metadata for a subset of columns/row groups? Right now `ParquetMetaData` has apis in terms of 'row group index' (and column index) https://github.com/apache/arrow-rs/blob/e9ea12b138f8fa11c6046e94cb2b55b2830a0d7c/parquet/src/file/metadata/mod.rs#L243-L247 SO if we only got the RowGroupMetadata for 1 Row Group from a file with 10 Row Groups what would `metadata.num_row_groups()` return? The same question applies to columns chunks too I think -- This is an automated message from the Apache Git Service.
