Github user hmcl commented on the issue: https://github.com/apache/storm/pull/1587 @darionyaphet can you please clarify why this patch is needed? In my understanding it shouldn't be necessary to have any logic for auto commit interval. If one wishes to set the auto commit interval, one can do so using the kafka properties `autocommit.interval.ms` and `autocommit.enable`. These properties will then be passed the `KafkaConsumer` [here](https://github.com/apache/storm/blob/master/external/storm-kafka-client/src/main/java/org/apache/storm/kafka/spout/KafkaSpout.java#L350) The [commit timer](https://github.com/apache/storm/blob/master/external/storm-kafka-client/src/main/java/org/apache/storm/kafka/spout/KafkaSpout.java#L111) is only used when in non auto commit mode. The 500 is only the initial delay. One can make this initial delay configurable, but it may not be of extreme importance to do so.
