[ANNOUNCE] Apache Kafka 2.2.0
The Apache Kafka community is pleased to announce the release for Apache
Kafka 2.2.0
- Added SSL support for custom principal name
- Allow SASL connections to periodically re-authenticate
- Command line tool bin/kafka-topics.sh adds AdminClient support
- Improved consumer group management
- default group.id is `null` instead of empty string
- API improvement
- Producer: introduce close(Duration)
- AdminClient: introduce close(Duration)
- Kafka Streams: new flatTransform() operator in Streams DSL
- KafkaStreams (and other classed) now implement AutoClosable to
support try-with-resource
- New Serdes and default method implementations
- Kafka Streams exposed internal client.id via ThreadMetadata
- Metric improvements: All `-min`, `-avg` and `-max` metrics will now
output `NaN` as default value
All of the changes in this release can be found in the release notes:
https://www.apache.org/dist/kafka/2.2.0/RELEASE_NOTES.html
You can download the source and binary release (Scala 2.11 and 2.12)
from: https://kafka.apache.org/downloads#2.2.0
---------------------------------------------------------------------------------------------------
Apache Kafka is a distributed streaming platform with four core APIs:
** The Producer API allows an application to publish a stream records to
one or more Kafka topics.
** The Consumer API allows an application to subscribe to one or more
topics and process the stream of records produced to them.
** The Streams API allows an application to act as a stream processor,
consuming an input stream from one or more topics and producing an
output stream to one or more output topics, effectively transforming the
input streams to output streams.
** The Connector API allows building and running reusable producers or
consumers that connect Kafka topics to existing applications or data
systems. For example, a connector to a relational database might
capture every change to a table.
With these APIs, Kafka can be used for two broad classes of application:
** Building real-time streaming data pipelines that reliably get data
between systems or applications.
** Building real-time streaming applications that transform or react
to the streams of data.
Apache Kafka is in use at large and small companies worldwide, including
Capital One, Goldman Sachs, ING, LinkedIn, Netflix, Pinterest, Rabobank,
Target, The New York Times, Uber, Yelp, and Zalando, among others.

Hello Mickael,
Thanks for reporting this, I double checked the release process and it is
indeed mentioned:
https://cwiki.apache.org/confluence/display/KAFKA/Release+Process
@Matthias J Sax <ma...@confluent.io> : I've copied the javadocs from
release repo to kafka-site github and it should have fixed it now.

Posted by Mickael Maison <mi...@gmail.com>.
Thanks Matthias for running this release!
The links to the 2.2 javadocs are broken:
https://kafka.apache.org/22/javadoc/index.html
The same happened for 2.1.0
(https://lists.apache.org/thread.html/57f2940225bcce36c3a01ec524dc967e81cb20e159d9b1c851b712f4@%3Cdev.kafka.apache.org%3E)
so we probably want to review this part of the release process.
