Jason Gustafson commented on KAFKA-4106:
----------------------------------------
[~fhussonnois] I think you might be able to do this already if you have your
{{PartitionAssignor}} implement {{org.apache.kafka.common.Configurable}}.
> Consumer / add configure method to PartitionAssignor interface
> --------------------------------------------------------------
>
> Key: KAFKA-4106
> URL: https://issues.apache.org/jira/browse/KAFKA-4106
> Project: Kafka
> Issue Type: Improvement
> Components: clients, consumer
> Affects Versions: 0.10.0.1
> Reporter: Florian Hussonnois
> Priority: Minor
>
> Currently, we can implement a custom PartitionAssignor which will forward
> user data that will be used during the assignments protocol. For example,
> data can be used to implement a rack-aware assignor
> However, currently we cannot dynamically configure a PartitionAssignor
> instance.
> It would be nice to add a method configure(Map<String, Object config) to the
> PartitionAssignor interface. Then, this method will be invoked by the
> KafkaConsumer on each assignor, as this is do for deserializers.
> The code modifications are pretty straight-forward but involve modifying the
> public interface PartitionAssignor. Does that mean this JIRA needs a KIP ?
> I can contribute to that improvement.
