- Every change that a load makes to a segment produces redo so the copy built from that redo holds the loaded rows without a later repair step
- Every change that a load makes to a segment produces an undo record so the copy built from that undo holds the loaded rows in commit order
- Every change that a load makes to a segment produces a checkpoint so the copy built from that checkpoint holds the loaded rows at a known position
- Every change that a load makes to a segment produces a flashback image so the copy built from that image holds the loaded rows before the load
