             Summary: MVCC TX: Rework UpdateSourceIterator to mix operation types
                 Key: IGNITE-10576
                 URL: https://issues.apache.org/jira/browse/IGNITE-10576
             Project: Ignite
          Issue Type: Bug
          Components: mvcc
            Reporter: Igor Seliverstov
            Assignee: Andrew Mashenkov


Current the UpdateSourceIterator implementation doesn't suit Cache API needs. It should be able to mix operation types per key.

For example we may execute putAll operation with a half of keys are having values and a half aren't, this way we should mix DELETE operation for null-value keys and PUT operation for others.

Another use case is a transform operation which should turn into a number of PUT/UPDATE/DELETE operations on a backup node.
