> Key: KAFKA-6382
> URL: https://issues.apache.org/jira/browse/KAFKA-6382
> Project: Kafka
> Issue Type: Improvement
> Components: clients
> Affects Versions: 1.0.0
> Reporter: Matthias J. Sax
> Assignee: Matthias J. Sax
> Priority: Minor
> Labels: kip
> Fix For: 1.1.0
>
>
> Constructors of {{ProducerConfig}} and {{ConsumerConfig}} are not public atm.
> This makes it hard to access default values for configurations. For Kafka
> Streams, we need access to those default value sometime and are forces to
> hardcode them via c&p atm.
