[VOTE] 2.1.0 RC0
Hello Kafka users, developers and client-developers,
This is the first candidate for feature release of Apache Kafka 2.1.0.
This is a major version release of Apache Kafka. It includes 28 new KIPs and
critical bug fixes. Please see the Kafka 2.1.0 release plan for more
details:
*https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=91554044*
<https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=91554044>
Here are a few notable highlights:
- Java 11 support
- Support for Zstandard, which achieves compression comparable to gzip with
higher compression and especially decompression speeds(KIP-110)
- Avoid expiring committed offsets for active consumer group (KIP-211)
- Provide Intuitive User Timeouts in The Producer (KIP-91)
- Kafka's replication protocol now supports improved fencing of zombies.
Previously, under certain rare conditions, if a broker became partitioned
from Zookeeper but not the rest of the cluster, then the logs of replicated
partitions could diverge and cause data loss in the worst case (KIP-320)
- Streams API improvements (KIP-319, KIP-321, KIP-330, KIP-353, KIP-356)
- Admin script and admin client API improvements to simplify admin
operation (KIP-231, KIP-308, KIP-322, KIP-324, KIP-338, KIP-340)
- DNS handling improvements (KIP-235, KIP-302)

Hey everyone,
Thanks for your help with testing the release! It has taken us some time to
validate the system tests for 2.1.0, fix flaky test and discuss/fix upgrade
note. All these issues are resolved now.
I have started another email thread to vote for 2.1.0 RC1. Please help test
and vote for RC1 when you get time. Hopefully we can officially release
Apache Kafka 2.1.0 next week.
Cheers,
Dong

Hey Mani,
Thanks again for catching this. The issue has been fixed and the configs
are properly displayed in
http://kafka.apache.org/20/documentation.html#producerconfigs now.
Thanks,
Dong

Hey Mani,
Thanks for catching these! Since kafka-site (
https://github.com/apache/kafka-site) can be updated separately of the
kafka release, I will file ticket and fix these later.
Thanks,

Hey Eno,
Thanks for the test! Yes https://builds.apache.org/job/kafka-2.1-jdk8 also
shows flaky test. It does not block the release. I will create ticket for
them and we will fix these one by one later.
Thanks,
Dong
