[VOTE] 2.3.0 RC1
Hi all,
This is the first candidate for the release of Apache Kafka 2.3.0.
This release includes many new features, including:
* Support for incremental cooperative rebalancing
* An in-memory session store and window store for Kafka Streams
* An API for allowing users to determine what operations they are authorized to perform on topics.
* A new broker start time metric.
* The ability for JMXTool to connect to secured RMI ports.
* A new and improved API for setting topic and broker configurations.
* Support for non-key joining in KTable.
* The ability to track the number of partitions which are under their min ISR count.
* The ability for consumers to opt out of automatic topic creation, even when it is enabled on the broker.
* The ability to use external configuration stores.
* Improved replica fetcher behavior when errors are encountered.
Check out the release notes for the 2.3.0 release here:
https://home.apache.org/~cmccabe/kafka-2.3.0-rc1/RELEASE_NOTES.html
The vote will go until Friday, June 7th, or until we create another RC.
* Kafka's KEYS file containing PGP keys we use to sign the release can be found here:
https://kafka.apache.org/KEYS
* The release artifacts to be voted upon (source and binary) are here:
https://home.apache.org/~cmccabe/kafka-2.3.0-rc1/
* Maven artifacts to be voted upon:
https://repository.apache.org/content/groups/staging/org/apache/kafka/
* Javadoc:
https://home.apache.org/~cmccabe/kafka-2.3.0-rc1/javadoc/
* The tag to be voted upon (off the 2.3 branch) is the 2.3.0 tag:
https://github.com/apache/kafka/releases/tag/2.3.0-rc1
thanks,
Colin

Hey Colin and Jason,
I would like to mention that https://issues.apache.org/jira/browse/KAFKA-8500 could also potentially be a blocker. The PR is ready for review: https://github.com/apache/kafka/pull/6899

Hi Colin,
After looking at these issues a little more, we do not believe they are
blockers for the release.

If we get in KAFKA-8487, we may as well do KAFKA-8386 since it causes a
similar problem. The patch is ready to be merged.

Hello Colin,
I caught an issue which would affect KIP-345 (
https://issues.apache.org/jira/browse/KAFKA-8487) and hence may need to be
considered a blocker for this release.

One small correction here: support for non-key joining (KIP-213) slipped from 2.3 due to time constraints.
