>             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.
