Vladislav Pyatkov commented on IGNITE-13265:
--------------------------------------------
[~ascherbakov] I answered you in PR.
More over I try to explain comments here:
1. It guarantees nothing, but makes a skip of record less probably during
historical rebalance.
2. I think this behavior was applying earlier and goes out of scope this
ticket. But if I correct realize you want to go through over whole WAL history,
this cannot be more effective.

> 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.
