Marcel Reutegger updated OAK-1981:
----------------------------------
Fix Version/s: 1.2
> Implement full scale Revision GC for DocumentNodeStore
> ------------------------------------------------------
>
> Key: OAK-1981
> URL: https://issues.apache.org/jira/browse/OAK-1981
> Project: Jackrabbit Oak
> Issue Type: New Feature
> Components: mongomk
> Reporter: Chetan Mehrotra
> Fix For: 1.2
>
>
> So far we have implemented garbage collection in some form with OAK-1341.
> Those approaches help us remove quite a bit of garbage (mostly due to deleted
> nodes) but till some part is left
> However full GC is still not performed due to which some of the old revision
> related data cannot be GCed like
> * Revision info present in revision maps of various commit roots
> * Revision related to unmerged branches (OAK-1926)
> * Revision data created to property being modified by different cluster nodes
> So having a tool which can perform above GC would be helpful. For start we
> can have an implementation which takes a brute force approach and scans whole
> repo (would take quite a bit of time) and later we can evolve it. Or allow
> system admins to determine to what level GC has to be done
