> We can significantly minimize amount of network traffic and GC pressure for
> the most frequent ATOMIC cache scenario - update with a single key.
> To achieve this we must add special versions of all update request/responses
> as well as corresponding futures.
> Furthermore, we should not create KV maps for single-key operations.
