> Key: KAFKA-4752
> URL: https://issues.apache.org/jira/browse/KAFKA-4752
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 0.10.3.0
> Reporter: Damian Guy
> Assignee: Eno Thereska
> Priority: Minor
> Fix For: 0.10.3.0
>
>
> When benchmarking join operations via the {{SimpleBenchmark}} we produce 2 * {{numRecords}}, i.e, {{numRecords}} to topic1 and {{numRecords}} to topic2.
> The {{CountDownLatch}} in the {{foreach}} keeps processing until it has received {{numRecords}}. As this is the {{numRecords}} produced from the join, the size of each record will either be {{VALUE_SIZE}} or {{2 * VALUE_SIZE}}. The MB/s calculation doesn't take this into account.
