>                 URL: https://issues.apache.org/jira/browse/IGNITE-18814
>             Project: Ignite
>          Issue Type: Bug
>            Reporter: Ivan Bessonov
>            Assignee: Vladislav Pyatkov
>            Priority: Critical
>              Labels: ignite-3
>             Fix For: 3.0.0-beta2
>
>          Time Spent: 50m
>  Remaining Estimate: 0h
>
> *Motivation*
> {code:java}
> MvPartitionStorage storage = listener.getMvStorage();
> if (hash == 0) {
>     hash = storage.hashCode();
> } else if (hash != storage.hashCode()) {
>     return false;
> }{code}
> This code is wrong, hash code is not defined for storage.
> *Implementation notes*
> To summarize all the mentioned before, the main issue is finding a way to 
> compare data stored in different replicas.
> The obvious approach to calculate hash all object that stored in each replica 
> storage. But the implementation can be difficult and time expensive in the 
> test.
> The easy way to compare stored indexies ( 
> _MvPartitionStorage#lastAppliedIndex_ , _MvPartitionStorage#persistedIndex_). 
> The both are applicable for comparison, but _persistedIndex_ upgrades latter.
> {code}
> MvPartitionStorage storage = listener.getMvStorage();
> if (idx == 0) {
>     idx = storage.persistedIndex();
> } else if (idx != storage.persistedIndex()) {
>     return false;
> }
> {code}
