----------------------------------

             Summary: [discovery] Increase default heartbeatInterval from 15s to 30s and timeout from 45s to 60s
                 Key: SLING-3396
                 URL: https://issues.apache.org/jira/browse/SLING-3396
             Project: Sling
          Issue Type: Task
          Components: Extensions
    Affects Versions: Discovery Impl 1.0.2
            Reporter: Stefan Egli
            Assignee: Stefan Egli


The default for heartbeatInterval is 15sec currently. This is rather fast and should be lowered to 30sec. The default heartbeatTimeout can also be upped from 45sec to 60sec. Note that this lowered chattyness and provides higher stability in high-load situations, but also increases reaction time slightly when an instance indeed crashes.
