Description
Rather than polling DescribeGraph every scrape_interval seconds, just call it once at startup, cache the state, then subscribe to graph notifications and update the cached state.
Rationale: DescribeGraph is an expensive call, so this optimization should reduce memory usage.

Research direction
Start by locating GraphCollector and its DescribeGraph polling path, then trace how graph notifications can be subscribed to. Done means the graph is described once at startup, the cached state is updated from notifications, and repeated scrape-interval polling is removed.
