> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core, mongomk
> Reporter: Marcel Reutegger
> Assignee: Marcel Reutegger
> Labels: concurrency
> Fix For: 1.3.0, 1.2.3, 1.0.15

>
> The DocumentNodeStoreBranch retries merges in two phases. First it retries
> merges while holding the merge lock non-exclusive and performing sleeps
> between attempts. If those retries fail the next phase will acquire the merge
> lock exclusively and perform retries. In the first phase the merge lock is
> released when the commit goes to sleep, while in the second it is not and may
> block other commits while sleeping.
> DocumentNodeStoreBranch should be changed to release the exclusive lock when
> the commit goes to sleep.
