---------------------------------
Summary: 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.
