> Key: IGNITE-18843
> URL: https://issues.apache.org/jira/browse/IGNITE-18843
> Project: Ignite
> Issue Type: Bug
> Reporter: Kirill Tkalenko
> Assignee: Kirill Tkalenko
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0.0-beta2
>
>
> It is necessary to slightly correct the behavior of the
> *org.apache.ignite.internal.storage.MvPartitionStorage#pollForVacuum* when we
> are trying to delete the same *RowVersion* in parallel.
> At the moment, when trying to delete 2 *RowVersion* in parallel, we will
> actually delete the first *RowVersion* for one thread, and the second thread
> will notice this and simply return *null*, and as a result, we will have one
> *RowVersion* that needs to be deleted.
> We need to try to get *RowVersion*s until the queue is empty.
> It needs to be fixed for all implementations.
