36/// This data structure contains an adjacency list of
37/// backfill nodes.
38/// Each edge represents a backfill order.
39/// For instance, given:
40/// `BackfillOrders[1] = [2, 3, 4]`
41/// It means that node 1 must be backfilled before nodes 2, 3, and 4.
42/// Concretely, these node ids are the fragment ids.
43/// This is because each fragment will only have 1 stream scan,
44/// and stream scan corresponds to a backfill node.
