Chetan Mehrotra commented on OAK-5898:
--------------------------------------
[~mreutegg] Can this tool be used with older versions of Oak (< 1.7.0)? If it
does not modify the data model but just reset the revision commit root values
then it would benefit older versions also
> Revision GC command line tool

> Issue Type: New Feature

> Revision GC can be triggered on a DocumentNodeStore on each node in a
> cluster. A common setup with Apache Sling on top of Oak has a scheduled task
> for the leader node in a cluster that triggers the Revision GC once a day.
> For testing, maintenance and operational purpose it would be good to have an
> alternative that can be triggered from the command line.
> A potential solution is a new run mode in oak-run. It would bootstrap a
> DocumentStore implementation (MongoDB or RDB) with a read-only
> DocumentNodeStore and run revision GC. The command should probably support
> options like:
> - maxRevisionAge as defined in VersionGarbageCollector.gc()
> - maxGCTime that limits the time GC will run until it will be canceled
> automatically.
> - delay as proposed in OAK-4780
