> In the UI, the Topology Page and the Component Page each make a getTopologyInfoWithOpts thrift call to nimbus for executor heartbeat data. Metrics from this data are then aggregated in by the UI daemon for display.
> When large topologies, with high-connectedness, are viewed in this way, the load times for each page can be minutes long.  In addition, heap usage by the nimbus JVM can grow substantially as data for each executor, component, & stream is serialized to be sent to the UI.
