What is this change for? It looks like it just moved from
topology-visualization-template to a new
topology-visualization-container-template, that is now loaded through AJAX.
> UI Topology & Component Pages have long load times with large,
> highly-connected Topologies

> Key: STORM-820
> URL: https://issues.apache.org/jira/browse/STORM-820
> Project: Apache Storm
> Issue Type: Improvement
> Affects Versions: 0.11.0
> Reporter: Derek Dagit
> Assignee: Derek Dagit
>
> 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.
