---------------------------------
Summary: SegmentMK: Implement garbage collection
Key: OAK-631
URL: https://issues.apache.org/jira/browse/OAK-631
Project: Jackrabbit Oak
Issue Type: Sub-task
Components: segmentmk
Reporter: Jukka Zitting
Priority: Minor
The SegmentMK architecture allows segment-level garbage collection by looking
at the cross-segment reference graph. A simple garbage collector would list all
segments, remove those that are reachable through the graph starting from one
of the journals, and finally remove all remaining segments.
Some "don't collect" flag or minimum lifetime information should be added to
segments that are currently being written so they don't get removed before they
get committed and thus referenced by a journal.
