------------------------------------
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.
