--------------------------------
Resolution: Fixed
> One producer per thread for Kafka Streams EOS
> ---------------------------------------------
>
> Key: KAFKA-8587
> URL: https://issues.apache.org/jira/browse/KAFKA-8587
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Boyang Chen
> Assignee: Boyang Chen
> Priority: Major
>
> Currently exactly-once producer is coupled with individual input partitions.
> This is not a well scaled solution for client application such as Kafka
> Streams, and the root cause is that EOS producer doesn't understand the topic
> partition move throughout consumer group rebalance. By amending this semantic
> gap, we could achieve much better EOS scalability.
