> On a historical rebalance some updates move from one node to another wherein this update may have various order in nodes. Reordering can happen in smell interval, but it cannot avoid at all in current implementation atomic protocol.
> This mean we will reduce a probably of loosing update if we make a margin from initial counter for the historical iterator on atomic cache.
