> Key: ARROW-5258
> URL: https://issues.apache.org/jira/browse/ARROW-5258
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++, Python
> Reporter: Pearu Peterson
> Assignee: Pearu Peterson
> Priority: Major
>
> This issue resolves partly the issue raised in ARROW-1983 by providing a way to collect FileMetaData objects of dataset pieces created via `write_to_dataset` function:
> {noformat}
> metadata_list = []
> write_to_dataset(table, ..., metadata_collector=metadata_list)
> {noformat}
> where `metadata_list` will contain instances of file metadata objects of dataset pieces.
