> Key: ARROW-8318
> URL: https://issues.apache.org/jira/browse/ARROW-8318
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Francois Saint-Jacques
> Assignee: Francois Saint-Jacques
> Priority: Major
> Labels: dataset
>
> Fragments are created on the fly when invoking a Scan. This means that a lot
> of the auxilliary/ancilliary data must be stored by the specialised Dataset,
> e.g. the FileSystemDataset must hold the path and partition expression. With
> the venue of more complex Fragment, e.g. ParquetFileFragment, more data must
> be stored.
