Nikolay Izhikov updated IGNITE-20718:
-
Description:
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.
was:
Snapshots supports {{snapshotTransferRate}} distributed property to limit
amount of bytes written by snapshot creation process to the disk.
Dump must use same property to limit disc usage while creating dumps.
