+ 1 (non-binding) Verifications: 1. I ran a produce-consume workload with plaintext auth, JDK17, zstd compression using an open messaging benchmark and found 3.6 to be better than or equal to 3.5.1 across all dimensions. Notably, 3.6 had consistently 6-7% lower CPU utilization, lesser spikes on P99 produce latencies and overall lower P99.8 latencies.
2. I have verified that detached signature is correct using https://www.apache.org/info/verification.html and the release manager public keys are available at https://keys.openpgp.org/search?q=F65DC3423D4CD7B9 3. I have verified that all metrics emitted in 3.5.1 (with Zk) are also being emitted in 3.6.0 (with Zk). Problems (but not blockers): 1. Metrics added in https://github.com/apache/kafka/commit/2f71708955b293658cec3b27e9a5588d39c38d7e aren't available in the documentation (cc: Justine). I don't consider this as a release blocker but we should add it as a fast follow-up. 2. Metric added in https://github.com/apache/kafka/commit/a900794ace4dcf1f9dadee27fbd8b63979532a18 isn't available in documentation (cc: David). I don't consider this as a release blocker but we should add it as a fast follow-up. -- Divij Vaidya On Mon, Oct 2, 2023 at 9:50 AM Federico Valeri <fedeval...@gmail.com> wrote: > Hi Satish, I did the following to verify the release: > > - Built from source with Java 17 and Scala 2.13 > - Ran all unit and integration tests > - Spot checked documentation > - Ran custom client applications using staging artifacts on a 3-nodes > cluster > - Tested tiered storage with one of the available RSM implementations > > +1 (non binding) > > Thanks > Fede > > On Mon, Oct 2, 2023 at 8:50 AM Luke Chen <show...@gmail.com> wrote: > > > > Hi Satish, > > > > I verified with: > > 1.
