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

             Summary: Validate baseline topology change history during node joins
                 Key: IGNITE-5854
                 URL: https://issues.apache.org/jira/browse/IGNITE-5854
             Project: Ignite
          Issue Type: New Feature
          Components: persistence
    Affects Versions: 2.1
            Reporter: Alexey Goncharuk
             Fix For: 2.2


It is possible to have a cluster-split restarts when persistence enabled:
Start 1, 2, 3, 4, update data. Stop
Start 1, 2. Update data. Stop
Start 3, 4. Update data. Stop.
Start 1, 2, 3, 4. Stop

We need to make sure that the second start is not allowed. This can be done by introducing
baseline topology history and topology hash generation.
