Chetan Mehrotra commented on OAK-3588:
--------------------------------------
[~mduerig] [~alex.parvulescu] I think we should make the lock fair (at minimum on trunk) and
see how systems work for next 1-2 release and then see if this change (enabling this by default)
is safe to backport
> SegmentNodeStore allow tweaking of lock fairness

> 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).
