             Summary: Atomic update requests should always use topology mappings instead of affinity
                 Key: IGNITE-7882
                 URL: https://issues.apache.org/jira/browse/IGNITE-7882
             Project: Ignite
          Issue Type: Bug
          Components: cache
    Affects Versions: 2.4
            Reporter: Pavel Kovalenko
            Assignee: Pavel Kovalenko


Currently for mapping cache atomic updates we can use two ways:
1) Use nodes reporting status OWNING for partition where we send the update.
2) Use only affinity nodes mapping if rebalance is finished.

Using the second way we may route update request only to affinity node, while there is also node which is still owner and can process read requests.

It can lead to reading null values for some key, while update for such key was successful a moment ago.
