[jira] [Commented] (CAY-1879) Concurrent non-blocking read-only DataContext

    [ https://issues.apache.org/jira/browse/CAY-1879?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13812385#comment-13812385 ] 

Andrus Adamchik commented on CAY-1879:
--------------------------------------

We may see some improvement by starting to use ReadWriteLock in the ObjectStore (to make 'getNode' more concurrent), however in my tests the real noticeable blocking happens only when we would need the "write" lock to load query results. So this will only be a negligible improvement.
