-------------------------------------
Summary: Revision GC command line tool
Key: OAK-5898
URL: https://issues.apache.org/jira/browse/OAK-5898
Project: Jackrabbit Oak
Issue Type: New Feature
Components: documentmk, run
Reporter: Marcel Reutegger
Fix For: 1.8
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
