Tzu-Li (Gordon) Tai commented on FLINK-3398:
--------------------------------------------
[~StephanEwen] That's actually a very good summary! From the usage pattern, I
think it makes sense. Our Kafka consumers are using "group.id" for start offset
& offset committing only, so the change will also fit into the current
implementation.
However, this again is stretching Kafka's original intent of the "group.id"
config. I think we need to decide whether or not these Flink-specific
behaviours should be separated apart from Kafka's original configs.
> Flink Kafka consumer should support auto-commit opt-outs

> Key: FLINK-3398
> URL: https://issues.apache.org/jira/browse/FLINK-3398
> Project: Flink
> Issue Type: Improvement
> Components: Kafka Connector
> Reporter: Shikhar Bhushan
> Fix For: 1.2.0
>
>
> Currently the Kafka source will commit consumer offsets to Zookeeper, either
> upon a checkpoint if checkpointing is enabled, otherwise periodically based
> on {{auto.commit.interval.ms}}
> It should be possible to opt-out of committing consumer offsets to Zookeeper.
> Kafka has this config as {{auto.commit.enable}} (0.8) and
> {{enable.auto.commit}} (0.9).
