I was thinking about this last night -- what I would suggest for this is to make functions like this for each type of https://docs.rs/parquet/latest/parquet/file/statistics/struct.ValueStatistics.html ```rust /// Returns an iterator over min values stored in `ValueStatistics<i32>` fn extract_i32_mins(stats: impl IntoIterator<&Statistics>) -> impl Iterator<Item = Option<i32>> { ... } ``` And then with those iterators, we can make the arrays directly something like ```rust let Int32ArrayMins = Int32Aray::from_iter(extract_i32_mins(stats)); ``` I think that would be both simple and fast. -- This is an automated message from the Apache Git Service.
