Ismaël Mejía commented on BEAM-4822:
------------------------------------
I know this is not beamish, but I am wondering if we sould add a sort of
Map<String, String> for all the 'filesystem' extended (and specific)
properties. Otherwise we will keep working the Coders. And additionally we
could improve the FileIO.match API to better filter for those. Pinging
[[email protected]] because he could be interested in this too.
> Beam FileIO should support versioned file systems

> Project: Beam
> Issue Type: New Feature
> Components: io-java-files
> Reporter: Reuven Lax
> Assignee: Chamikara Jayalath
> Priority: Major
>
> Some file systems (e.g. GCS) are versioned, and support reading previous
> generations of files. Since Beam's file support does not currently support
> this concept, the latest versions of files are always the ones returned.
> Users should be able to specify that they want to read a previous version of
> a file in FileIO.
