> Key: ARROW-3774
> URL: https://issues.apache.org/jira/browse/ARROW-3774
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Uwe L. Korn
> Priority: Major
> Labels: parquet
>
> Instead of creating a chunk per RowGroup, we should read at least for
> primitive type into a single, pre-allocated Array. This needs some new
> functionality in the Record reader classes and thus should be done after
> https://github.com/apache/parquet-cpp/pull/462 is merged.
