Damian Guy created KAFKA-4752:
---------------------------------
Summary: Streams Simple Benchmark MB/sec calculation is not
correct for Join operations
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.
