Michael Dürig commented on OAK-7234:
------------------------------------
Blocking this on OAK-7866 for now so we won't end up with a repository that
does not start up without having a tool to resolve the situation.
> Check for outdated journal at startup

> Key: OAK-7234
> URL: https://issues.apache.org/jira/browse/OAK-7234
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: segment-tar
> Reporter: Michael Dürig
> Assignee: Michael Dürig
> Priority: Minor
> Labels: resilience, tooling
> Fix For: 1.10

>
> To prevent accidentally branching the repository when the {{journal.log}}
> became outdated (e.g. OAK-3702) we could add an additional safety feature
> which would prevent the repository from starting in such cases. There's a
> couple of concerns to address:
> * What kind of tooling / guidance do we need to provide to recover should
> such a situation be detected?
> * How do we detect the {{journal.log}} being outdated?
> * How do we prevent false positives?
> * How do we deal with situation where the {{journal.log}} modifications are
> intended (e.g. by tools, of manual interventions)?
