I think the functionality is very desirable. In many cases, you really
don't want Flink to write something to Zookeeper for some random GroupId. This
floods ZooKeeper with garbage that helps no one.
I think that this is actually a kind of nice solution. The
`auto.commit.enable` in Flink means not necessary periodically, but "on
checkpoint or periodically".

> Reporter: Shikhar Bhushan
>
> 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).
