Geoff Anderson updated KAFKA-2489:
----------------------------------
Fix Version/s: 0.8.3
> System tests: update benchmark tests to run with new and old consumer
> ---------------------------------------------------------------------
>
> Key: KAFKA-2489
> URL: https://issues.apache.org/jira/browse/KAFKA-2489
> Project: Kafka
> Issue Type: Bug
> Reporter: Geoff Anderson
> Assignee: Geoff Anderson
> Fix For: 0.8.3
>
>
> Update benchmark tests to run w/new consumer to help catch performance
> regressions
> For context:
> https://www.mail-archive.com/dev@kafka.apache.org/msg33633.html
> The new consumer was previously reaching getting good performance. However, a
> recent report on the mailing list indicates it's dropped significantly. After
> evaluation, even with a local broker it seems to only be reaching a 2-10MB/s,
> compared to 600+MB/s previously. Before release, we should get the
> performance
> back on par.
> Some details about where the regression occurred from the mailing list
> http://mail-archives.apache.org/mod_mbox/kafka-dev/201508.mbox/%3CCAAdKFaE8bPSeWZf%2BF9RuA-xZazRpBrZG6vo454QLVHBAk_VOJg%40mail.gmail.com%3E

> bq. At 49026f11781181c38e9d5edb634be9d27245c961 (May 14th), we went from good
> performance -> an error due to broker apparently not accepting the partition
> assignment strategy. Since this commit seems to add heartbeats and the server
> side code for partition assignment strategies, I assume we were missing
> something on the client side and by filling in the server side, things
> stopped
> working.
> bq. On either 84636272422b6379d57d4c5ef68b156edc1c67f8 or
> a5b11886df8c7aad0548efd2c7c3dbc579232f03 (July 17th), I am able to run the
> perf
> test again, but it's slow -- ~10MB/s for me vs the 2MB/s Jay was seeing, but
> that's still far less than the 600MB/s I saw on the earlier commits.
> Ideally we would also at least have a system test in place for the new
> consumer, even if regressions weren't automatically detected. It would at
> least
> allow for manually checking for regressions. This should not be difficult
> since
> there are already old consumer performance tests.
