Github user HeartSaVioR commented on the pull request: https://github.com/apache/storm/pull/268#issuecomment-59772115 Discussing 3 approaches seems interesting! I think it's key point about selecting approach. Does "replaying tuples with tuple timeout" make us feel safe? If we feel comfortable and safe with it, choosing approach A is no problem. If it doesn't, we need to choose approach B. In addition to aware of reassigning task, we need to choose approach C. Please correct me if I'm wrong.
