>
> We will have a concept of oldest Snapshot with compaction history. We will
> support efficient Snapdiffs from snapshots as old as this oldest with
> compaction history. We will delete SST file nodes in the compaction DAG that
> will not be used in any SnapDiff since this oldest retained Snapshot.
> We will continue to support SnapDiffs from older Snapshots as well. But they
> will iterate over all the keys in the namespace.
