> Refactor StreamsPartitionAssignor Repartition Count logic
> ---------------------------------------------------------
>
> Key: KAFKA-9377
> URL: https://issues.apache.org/jira/browse/KAFKA-9377
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Boyang Chen
> Assignee: feyman
> Priority: Major
>
> The current repartition count uses a big while loop to randomly initialize
> each repartition topic counts, which is error-prone and hard to maintain. A
> more intuitive and robust solution would be doing a DFS search from
> bottom-up, where we initialize all the sink nodes repartition topic counts by
> making sure all their parents are initialized.
