>
> We have some processing pipelines where we want to know the file path that
> each record being processed came from. It would be nice if this could be
> exposed to the DoFns in our pipelines.
>
> This same desire was expressed a little over 1 year ago on the mailing list:
> [http://mail-archives.apache.org/mod_mbox/crunch-user/201611.mbox/%3CCAG-tO+Y42KRFiocg1RJT4qFcyvkPjFSfZa4z=wk34arip4w...@mail.gmail.com%3E]
>
> Unfortunately, that thread dead-ended.
>
> I will use the comments section and a patch to propose a simple, albeit
> slightly hacky solution. Another alternative would be to create a new Source
> that provides a PCollection<Pair<Path, Record>>, but I'm not sure of the
> effort it would take to create that.
