-------------------------------
Status: Patch Available (was: Open)
> Disabling of auto commit is ignored during consumer group rebalancing
> ---------------------------------------------------------------------
>
> Key: KAFKA-919
> URL: https://issues.apache.org/jira/browse/KAFKA-919
> Project: Kafka
> Issue Type: Bug
> Components: consumer
> Affects Versions: 0.8
> Environment: java 7/linux
> Reporter: Phil Hargett
> Assignee: Neha Narkhede
> Attachments: kafka-919.patch

>
> From the mailing list:
> In one of our applications using Kafka, we are using the high-level consumer
> to pull messages from our topic.
> Because we pull messages from topics in discrete units (e.g., an hour's worth
> of messages), we want to control explicitly when offsets are committed.
> Even though "auto.commit.enable" is set to false, during consumer group
> rebalancing, offsets are committed anyway, regardless of the setting of this
> flag.
> Is this a bug? Or just a known gap in offset management? I do see plenty of
> notes on the wiki suggesting future releases may enable applications using
> the high-level consumer to have more fine-grained control over offset
> management.
> I also fully realize that different applications have different needs, and
> meeting all of them with a clean API can be challenging.
> In the case of this application, the high-level consumer solves the problem
> of locating the correct in a cluster for a given topic, so there are
> advantages to using it, even if we are not using it to balance fetch load
> across multiple consumers. We ideally have only 1 consumer active per
> consumer group, and can tolerate some duplicate messages. But, the consumer
> groups make it easy for 1 consumer to recover at the correct starting point,
> should the prior consumer in the group have failed before doing a commit.
