----------------------------------------
Summary: Fix the behavior of MvPartitionStorage#pollForVacuum when
trying to delete the same row in parallel
Key: IGNITE-18843
URL: https://issues.apache.org/jira/browse/IGNITE-18843
Project: Ignite
Issue Type: Bug
Reporter: Kirill Tkalenko
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.
