The Apache Kafka community is pleased to announce the release for Apache Kafka 1.0.1.
This is a bugfix release for the 1.0 branch that was first released with 1.0.0 about 4 months ago. We've fixed 49 issues since that release. Most of these are non-critical, but in aggregate these fixes will have significant impact. A few of the more significant fixes include: * KAFKA-6277: Make loadClass thread-safe for class loaders of Connect plugins * KAFKA-6185: Selector memory leak with high likelihood of OOM in case of down conversion * KAFKA-6269: KTable state restore fails after rebalance * KAFKA-6190: GlobalKTable never finishes restoring when consuming transactional messages * KAFKA-6529: Stop file descriptor leak when client disconnects with staged receives * KAFKA-6238: Issues with protocol version when applying a rolling upgrade to 1.0.0 All of the changes in this release can be found in the release notes: https://dist.apache.org/repos/dist/release/kafka/1.0.1/RELEASE_NOTES.html You can download the source release from: https://www.apache.org/dyn/closer.cgi?path=/kafka/1.0.1/kafka-1.0.1-src.tgz and binary releases from: https://www.apache.org/dyn/closer.cgi?path=/kafka/1.0.1/kafka_2.11-1.0.1.tgz (Scala 2.11) https://www.apache.org/dyn/closer.cgi?path=/kafka/1.0.1/kafka_2.12-1.0.1.tgz (Scala 2.12) --------------------------------------------------------------------------------------------------- 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.three key capabilities: 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.
