-----------------------------------------

             Summary: Remove contention on DS creation or removing
                 Key: IGNITE-5364
                 URL: https://issues.apache.org/jira/browse/IGNITE-5364
             Project: Ignite
          Issue Type: Improvement
            Reporter: Mikhail Cherkasov
            Assignee: Mikhail Cherkasov
             Fix For: 2.1


All DSs are stored in one Map which itself is stored in utilityCache, this makes high contention
on DS creation or removing, it requires lock on the key and manipulation with the Map under
the lock. So all threads in cluster should wait for this lock to create or remove DS.
