-------------------------------------
Summary: Improve concurrent merge handling
Key: OAK-1419
URL: https://issues.apache.org/jira/browse/OAK-1419
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core, mongomk
Reporter: Marcel Reutegger
Assignee: Marcel Reutegger
Priority: Minor
The MicroKernel and Document based NodeStore implementations currently perform
retries when a merge failed and the conflict was potentially introduced by a
commit hook or some external change not yet visible to the local cluster node.
After a number of retries the implementation gives up and throws an exception.
For the cluster local only merges the implementation could fall back to an
exclusive lock and serialize merges.
