get_fragment_to_relation_map

In the ddl backpressure graph, we want to compute the backpressure between relations. So we need to know which are the fragments which are connected to external relations. These fragments form the vertices of the graph. We can get collection of backpressure values, keyed by vertex_id-vertex_id. This function will return a map of fragment vertex id to relation id. We can convert fragment_id-fragment_id to relation_id-relation_id using that. Finally, we have a map of relation_id-relation_id to backpressure values.

get_relation_id_infos

Provides a hierarchy of relation ids to fragments to actors.

get_streaming_stats

NOTE(kwannoel): Although we fetch the BP for the entire graph via this API, the workload should be reasonable. In most cases, we can safely assume each node has most 2 outgoing edges (e.g. join). In such a scenario, the number of edges is linear to the number of nodes. So the workload is proportional to the relation id graph we fetch in get_relation_id_infos.
