             Summary: Proper handling of a rebalancing with disabled WAL
                 Key: IGNITE-13171
                 URL: https://issues.apache.org/jira/browse/IGNITE-13171
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.8
            Reporter: Alexey Scherbakov
            Assignee: Alexey Scherbakov
             Fix For: 2.9


Current implementation of a optimized rebalancing with disabled WAL used when all local partitions are MOVING and persistence is enabled has multiple flaws:
 # There are races between concurrent topology change and partition owning after a checkpoint causing consistency issues.
 # Partitions will not be owned after a topology has changed and new topology version is compatible with previous.

This is the reason for flaky tests [1] [2]
