-------------------------------------
Summary: Consider fair mode for backgroundOperationLock
Key: OAK-2768
URL: https://issues.apache.org/jira/browse/OAK-2768
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core, mongomk
Reporter: Marcel Reutegger
Assignee: Marcel Reutegger
Fix For: 1.3.0
The backgroundOperationLock in DocumentNodeStore uses the default non-fair
acquisition order. According to JavaDoc of ReentrantReadWriteLock it is
possible that a background operation task gets delayed for a long time when the
system is under load. We should probably consider using the fair mode for the
backgroundOperationLock to make sure background operation tasks do not get
delayed excessively.
