If an all-AMPs archive of a journal table is restored, the restored permanent journal goes to a different subtable than the journal currently writing the updates.
A restored journal overlays any change images that were restored to the same AMPs. During normal processing, the Teradata Database writes after-change images to a different processor than the one with the original data row. If after-change images from an archive are restored, the rows are written to the processor that contains the data row to which the change applies.
