> Prefix for sink task consumer groups should be configurable
> -----------------------------------------------------------
>
> Key: KAFKA-4400
> URL: https://issues.apache.org/jira/browse/KAFKA-4400
> Project: Kafka
> Issue Type: Bug
> Components: KafkaConnect
> Affects Versions: 0.10.1.0
> Reporter: Ewen Cheslack-Postava
> Assignee: Ewen Cheslack-Postava
>
> Currently the prefix for creating consumer groups is fixed. This means that
> if you run multiple Connect clusters using the same Kafka cluster and create
> connectors with the same name, sink tasks in different clusters will join the
> same group. Making this prefix configurable at the worker level would protect
> against this.
> An alternative would be to define unique cluster IDs for each connect
> cluster, which would allow us to construct a unique name for the group
> without requiring yet another config (but presents something of a
> compatibility challenge).
