> By looking at the Parquet statistics, a user can already determine with its
> own logic which RowGroups are interesting for him. Currently we only provide
> functions to read the whole file or individual RowGroups. By supplying
> {{parquet::arrow}} with the RowGroups at once, it can better optimize its
> memory allocations as well as make better use of the underlying thread pool.
