Igor Seliverstov updated IGNITE-10576:
--------------------------------------
Description:
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.
