[jira] [Created] (CAY-2446) Disjoint By Id queries run inside synchronized block

Nikita Timofeev created CAY-2446:
------------------------------------

             Summary: Disjoint By Id queries run inside synchronized block
                 Key: CAY-2446
                 URL: https://issues.apache.org/jira/browse/CAY-2446
             Project: Cayenne
          Issue Type: Improvement
          Components: Core Library
            Reporter: Nikita Timofeev
            Assignee: Nikita Timofeev
             Fix For: 4.1.M3


While researching lock contention in read-only mode I found that queries that are run for {{DisjoinById}} prefetches inside context-wide lock on {{ObjectStore}}. This can lead in really huge lock contention between threads concurrently reading from same context.
