the auto formatting could be improved :( Probably not worth your time to
do this as I face the same issue, and fall back to my own formatting.
> Store Kafka offsets with Kafka's consumer offset management api
> ---------------------------------------------------------------
>
> Key: STORM-1015
> URL: https://issues.apache.org/jira/browse/STORM-1015
> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-kafka
> Affects Versions: 0.11.0
> Reporter: Hang Sun
> Priority: Minor
> Labels: consumer, kafka, offset
> Original Estimate: 72h
> Remaining Estimate: 72h
>
> Current Kafka spout stores the offsets (and some other states) inside ZK with
> its proprietary format. This does not work well with other Kafka offset
> monitoring tools such as Burrow, KafkaOffsetMonitor etc. In addition, the
> performance does not scale well compared with offsets managed by Kafka's
> built-in offset management api. I have added a new option for Kafka to store
> the same data using Kafka's built-in offset management capability. The change
> is completely backward compatible with the current ZK storage option. The
> feature can be turned on by a single configuration option. Hope this will
> help people who wants to explore the option of using Kafka's built-in offset
> management api.
