The current `parquet::Statistics` implementation is tied to `TypeDefinedOrder`. We will also add a `IEEE754TotalOrder` as proposed by https://github.com/apache/parquet-format/pull/221. Perhaps we can refactor the `parquet::Statistics` to be aware of column order? For `TypeDefinedOrder` and `IEEE754TotalOrder`, `parquet::Statistics` collects all fields. For `UndefinedOrder`, the stats writes empty `min` and `max` but keeps other fields including null_count. cc @mapleFU -- This is an automated message from the Apache Git Service.
