Work on KAFKA-4752 started by Eno Thereska. ------------------------------------------- > 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
