---------------------------------------------
Summary: [C++][Dataset] Dataset should instantiate Fragment
Key: ARROW-8318
URL: https://issues.apache.org/jira/browse/ARROW-8318
Project: Apache Arrow
Issue Type: Improvement
Components: C++ - Dataset
Reporter: Francois Saint-Jacques
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.
