Joris Van den Bossche commented on ARROW-7677:
----------------------------------------------
It came up in a partitioned parquet dataset test:
https://github.com/apache/arrow/blob/aec37d768abbee3ea3ce4c32002462ff0e1c3674/python/pyarrow/tests/test_dataset.py#L627-L662
Quoting myself from the PR:
> From the discussion I think we thought the issue is coming from passing a
> base path path with backslashes to GetTargetStats, which is then leading to
> backslashes being used in the crawled file paths.
> partition discovery is not working with windows path, presumably because the
> path splitting doesn't work
> [C++] Handle Windows file paths with backslashes in GetTargetStats

> Currently, if the base path passed to {{GetTargetStats}} has backslashes,
> the produces FileStats also include them, resulting in some other
> functionality (such as splitting the path) not working.
