alamb opened a new issue #55: URL: https://github.com/apache/arrow-rs/issues/55
*Note*: migrated from original JIRA: https://issues.apache.org/jira/browse/ARROW-6774 Using the example at [https://github.com/apache/arrow/tree/master/rust/parquet] is slow. The snippet {code:none} let reader = SerializedFileReader::new(file).unwrap(); let mut iter = reader.get_row_iter(None).unwrap(); let start = Instant::now(); while let Some(record) = iter.next() {} let duration = start.elapsed(); println!("{:?}", duration); {code} Runs for 17sec for a ~160MB parquet file. If there is a more effective way to load a parquet file, it would be nice to add it to the readme. P.S.: My goal is to construct an ndarray from it, I'd be happy for any tips. -- This is an automated message from the Apache Git Service.
