>
> There are several issues with partition update counters consistency in
> transactional caches. The next approach solves most of them:
> # Count per-partition updates
> # on prepare state on primary node update current partition counter
> incrementing it by per-partition updates count and send initial value with
> updates count to backup nodes
> # on backup nodes hold all pending updates and update partition update
> counter applying the lowest gapless update (on tx finish).
> # on historical rebalance use partition update counter as start point.
