----------------------------------
Summary: 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
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.
