Remi Dettai created ARROW-10620: ----------------------------------- Summary: [Rust][Parquet] move column chunk range logic to metadata.rs Key: ARROW-10620 URL: https://issues.apache.org/jira/browse/ARROW-10620 Project: Apache Arrow Issue Type: Bug Components: Rust Reporter: Remi Dettai
Getting the range of bytes of a column chunk inside a parquet file can be useful for external crates (for instance if they want to pre-fetch the columns), and is not completely obvious (it is enough to take a look at [1] and [2] to see that things can quickly get messy). I think it would be nice to move this logic in the metadata definition rather than have lost it in the middle of the reader implem.
