1.4
> Partial compaction
> ------------------
>
> Key: OAK-3349
> URL: https://issues.apache.org/jira/browse/OAK-3349
> Project: Jackrabbit Oak
> Issue Type: Sub-task
> Components: segmentmk
> Reporter: Michael Dürig
> Assignee: Michael Dürig
> Labels: compaction, gc
> Fix For: 1.4
>
>
> On big repositories compaction can take quite a while to run as it needs to
> create a full deep copy of the current root node state. For such cases it
> could be beneficial if we could partially compact the repository thus
> splitting full compaction over multiple cycles.
> Partial compaction would run compaction on a sub-tree just like we now run it
> on the full tree. Afterwards it would create a new root node state by
> referencing the previous root node state replacing said sub-tree with the
> compacted one.
> Todo: Asses feasibility and impact, implement prototype.
