[jira] [Updated] (IGNITE-8614) The atomic cache in inconsistent state

["Denis Garus (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IGNITE-8614?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Denis Garus updated IGNITE-8614:
--------------------------------
    Description: 
There is a situation when the atomic cache becomes inconsistent.
There are two nodes: Node_1 with primary partition and Node_2 with backup partition.
1. Node_3 is started;
2. Before a rebalance of the partition from Node_1 to Node_3 is occurred new value is put to the partition on Node_1;
3. Node_1 creates a future for a propagating new value to Node_2 and Node_3;
4. Node_3 gets new value from Node_1 in the process a rebalance;
5. Node_1 is stopped;
6. The future from step 3 is failed because of step 5. 
Now we have Node_3 with the new value and Node_2 with old value.

We need to find out the way to fix this inconsistent state and implement one.
