             Summary: Address possible data corruption in Persistent Store implementations
                 Key: IGNITE-3321
                 URL: https://issues.apache.org/jira/browse/IGNITE-3321
             Project: Ignite
          Issue Type: Improvement
          Components: cache
    Affects Versions: 1.6
         Environment: any
            Reporter: Alexandre Boudnik
            Assignee: Alexandre Boudnik


When records from partitions on different nodes are committed, each node uses its own SQL connection. It is possible that one of DML statements will fail on one of the connections, while others have committed successfully.

And we need to make a very hard decision:
- If we ignore fail then we will lose some changes.
- If we throw an exception we will make inconsistent changes.
