40/// This data structure contains an adjacency list of

42/// Each edge represents a backfill order.
43/// For instance, given:
44/// `BackfillOrders[1] = [2, 3, 4]`
45/// It means that node 1 must be backfilled before nodes 2, 3, and 4.
46/// Concretely, these node ids are the fragment ids.
47/// This is because each fragment will only have 1 stream scan,
48/// and stream scan corresponds to a backfill node.
