@choang: the refactored code is pushed
@erikdw: I was referring to the internal Json structure used to store
offsets as shown by example below:
{
"broker": {
"host": "kafka.sample.net",
"port": 9092
},
"offset": 4285,
"partition": 1,
"topic": "testTopic",
"topology": {
"id": "fce905ff-25e0 -409e-bc3a-d855f 787d13b",
"name": "Test Topology"
}
}
> 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.
