                 Key: IGNITE-12551
                 URL: https://issues.apache.org/jira/browse/IGNITE-12551

          Issue Type: Bug
          Components: persistence
    Affects Versions: 2.7.6
            Reporter: Alexey Scherbakov
            Assignee: Alexey Scherbakov
             Fix For: 2.9


Where is a possibility of partition desync in the following scenario:

1. Some partition is evicted with non zero counters.
2. It is owned again and are going to be rebalanced.
3. Some node in grid has history for the partition defined by it's (initial, current) counters pair.

In this scenario partition will be historically rebalanced having only partial data.
