Subject [ANNOUNCE] Apache Kafka 2.1.0
Date Wed, 21 Nov 2018 18:09:38 GMT
The Apache Kafka community is pleased to announce the release for Apache
Kafka 2.1.0


This is a major release and includes significant features from 28 KIPs. It
contains fixes and improvements from 179 JIRSs, including a few critical
bug fixes. Here is a summary of some notable changes

** 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)

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.
