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

             Summary: During rebalancing checkpoint read lock is acquired for each entry (twice).
                 Key: IGNITE-8019
                 URL: https://issues.apache.org/jira/browse/IGNITE-8019
             Project: Ignite
          Issue Type: Bug
            Reporter: Ilya Lantukh
            Assignee: Ilya Lantukh


In GridDhtPartitionDemander.preloadEntry(...) checkpointReadLock is acquired twice, which is definitely a mistake. But even acquiring it once per entry causes unnecessary contention - it should be taken once for SupplyMessage.
