[hibernate-issues] [Hibernate-JIRA] Resolved: (HSEARCH-272) Improve contention on DirectoryProviders in lucene backend

Improve contention on DirectoryProviders in lucene backend ---------------------------------------------------------- Key: HSEARCH-272 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-272 Project: Hibernate Search Issue Type: Improvement Components: engine Affects Versions: 3.1.0.Beta1 Reporter: Sanne Grinovero Assignee: Sanne Grinovero Fix For: 3.1.0.Beta2 Currently the lucene backend doesn't acquire locks on DirectoryProvider(s) until needed, but releases them only at end of all work. So having a workqueue affecting DP A and B in this order: ABBB will have this locking: lockA, doA, lockB, doB,doB,doB, unlockA, unlockB. instead, this would be desirable: lockA, doA, unlockA, lockB, doB,doB,doB, unlockB Side-effect is that something like ABAB will be reordered to AABB (keeping correct order from a DP point of view).
