> 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.
