> For the ORC file format, we return base {{Fragment}} objects instead of the {{FileFragment}} subclass (which has more functionality):
> {code:python}
> import pyarrow as pa
> import pyarrow.dataset as ds
> from pyarrow import orc
> table = pa.table({'a': [1, 2, 3]})
> orc.write_table(table, "test.orc")
> dataset = ds.dataset("test.orc", format="orc")
> fragment = list(dataset.get_fragments())[0]
> {code}
> {code}
> In [9]: fragment
> Out[9]: <pyarrow._dataset.Fragment at 0x7f97b159beb0>
> In [10]: fragment.path
> ---------------------------------------------------------------------------
> AttributeError                            Traceback (most recent call last)
> <ipython-input-10-6477cc57f0cc> in <module>
> ----> 1 fragment.path
> AttributeError: 'pyarrow._dataset.Fragment' object has no attribute 'path'
> {code}
