--------------------------------------
Issue Type: Improvement (was: Bug)
> MVCC TX: Rework UpdateSourceIterator to mix operation types
> -----------------------------------------------------------
>
> Key: IGNITE-10576
> URL: https://issues.apache.org/jira/browse/IGNITE-10576
> Project: Ignite
> Issue Type: Improvement
> Components: mvcc
> Reporter: Igor Seliverstov
> Assignee: Andrew Mashenkov
> Priority: Major
> Fix For: 2.8
>
>
> The current 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.
