Resolution: Invalid

> Primary copies of partitions don't contain entry duplicates.
> Because, entries can be filtered based on version on the creation time.
> So, during iteration we don't need to track possible duplicates inside
> {{DumpedPartitionIterator}} implementation in {{partKeys}} variable. This
> will decrease memory consumption and improve performance of dump iteration
> and therefore dump check procedures.
