Alex Parvulescu created OAK-3588:
------------------------------------

             Summary: SegmentNodeStore allow tweaking of lock fairness
                 Key: OAK-3588
                 URL: https://issues.apache.org/jira/browse/OAK-3588
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: segmentmk
            Reporter: Alex Parvulescu
            Assignee: Alex Parvulescu


This will expose the merge semaphores's fairness policy as the semaphore is currently configured as _NonfairSync_ (default value).
Opening this option will be beneficial in collecting more stats around thread starvation and what the best policy is (fair vs non fair).
