> Add liveliness monitoring for FileStore background operations
> ---------------------------------------------------------------

> Key: OAK-7854
> URL: https://issues.apache.org/jira/browse/OAK-7854
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: segment-tar
> Reporter: Michael Dürig
> Assignee: Michael Dürig
> Priority: Major
> Fix For: 1.10
>
>
> The FileStore background operations are ultimately executed through a
> {{ScheduledExecutorService}}. In the case this scheduling gets blocked (e.g.
> because of a deadlock or lock contention in one of its tasks) there is chance
> of repository corruption.
> To minimise potential data loss we should implement monitoring endpoints for
> the vital background operations. This would allow deployments to take action
> early in case of failures and thus minimise potential data loss and simplify
> recovery.
