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

             Summary: Iterator of Redis State may return same key multiple time, with different values
                 Key: STORM-2449
                 URL: https://issues.apache.org/jira/browse/STORM-2449
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-redis
    Affects Versions: 2.0.0, 1.1.0
            Reporter: Jungtaek Lim
            Assignee: Jungtaek Lim


Redis state iterator iterates pending prepare -> pending commit -> external storage (state) sequentially. While iterating, more of them are subject to change, so it can provide inconsistent result.

While we can't provide consistent result (since states are changing continuously), at least iterator needs to provide same key only once.
