Ismaël Mejía commented on BEAM-4822:
------------------------------------
We have the same requirement for S3. Will this imply modifying Metadata (as
happened with the lastModifiedDate) case recently? Any ideas already?
> Beam FileIO should support versioned file systems
> -------------------------------------------------

> Key: BEAM-4822
> URL: https://issues.apache.org/jira/browse/BEAM-4822
> 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.
