Michael Dürig commented on OAK-3804:
------------------------------------
Probably a good idea to have something like this for emergency recovery. We
should also make it resilient against all sort of errors (like
corrupted/missing tar files/segments). AFAICS currently it would just bail out
in such cases. Optimally it would just print a warning and continue with what
is there.

> There are cases where the flush thread apparently gets stuck (OAK-3303), this
> means that the journal file will not be updated resulting in loss of content
> as the journal file is the single source of truth.
> This oak run mode would be a best effort approach to parse the tar files and
> come out with (newer) candidates for root entries to the journal.
