Derek Dagit created STORM-599:
---------------------------------
Summary: UI is slow do to fetching heartbeats from ZK
Key: STORM-599
URL: https://issues.apache.org/jira/browse/STORM-599
Project: Apache Storm
Issue Type: Improvement
Affects Versions: 0.9.3
Reporter: Derek Dagit
Assignee: Derek Dagit
Priority: Minor
The method getTopologyInfo fetches every heartbeat from ZooKeeper in order to
gather statistics. The UI calls this method via thrift to render the topology
page.
When topologies are launched with thousands of executors, this fetching from ZK
dramatically slows things down.
