    Hi. STORM-2077 is being resolved here https://issues.apache.org/jira/browse/STORM-2087. Sorry for the inconvenience.
    
    I'm not sure I understand why adding manual partition management is necessary. Kafka has recently added heartbeating from a background thread, so it's no longer necessary to poll often in order to avoid rebalances (see http://kafka.apache.org/documentation.html#upgrade_1010_notable, search for "heartbeat"). That change decouples necessary poll frequency from the time it would take to detect a crashed consumer, so the `max.poll.interval.ms` can be bumped if a rebalance every 5 minutes is unacceptable (and then only if poll isn't called in that interval).
    
    Could you describe a use case?
