             Summary: Recipes such as TreeCache are susceptible to herding on reconnections
                 Key: CURATOR-441
                 URL: https://issues.apache.org/jira/browse/CURATOR-441
             Project: Apache Curator
          Issue Type: Improvement
          Components: Framework, Recipes
    Affects Versions: 4.0.0
            Reporter: Jordan Zimmerman
            Assignee: Jordan Zimmerman
            Priority: Minor
             Fix For: 4.0.1


Many of Curator's recipes (TreeCache, etc.) have to refresh their state when a connection problem is repaired. In larger systems, this could cause a thundering herd as all these clients press the ZK ensemble. It would be nice to introduce an optional Jitter mechanism into the Framework connection management so that reconnections aren't immediately reported to the recipes, but are instead delayed slightly with some randomness.
