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.
