-----------------------------------
Summary: Optmize query call for retrieving host information
Key: AMBARI-1460
URL: https://issues.apache.org/jira/browse/AMBARI-1460
Project: Ambari
Issue Type: Improvement
Components: client
Affects Versions: 1.2.2
Reporter: Yusaku Sako
Assignee: Yusaku Sako
Fix For: 1.2.2
Every 15 seconds, Ambari Web makes a call to retrieve information about all
hosts in the cluster. With 400+ nodes, this call retrieves about 10MB of info,
since the API returns last_agent_env, which is host check results used during
bootstrap and makes the payload huge.
By optimizing the query string for this API call, we can cut down on the
payload by more than 90%.
