The 4th Generation of Reactor is arriving. On behalf of the team we want to thank all our community for the tremendous feedback. Over the last year we have grown our reactive line-up significantly including R2DBC and BlockHound. Our adoption in the java ecosystem looks phenomenal and we are collaborating with major corps including Microsoft and Google. We have more than doubled our regular Gitter audience with some awesome -you guessed it- reactive discussions happening every day. Finally, Sergei Egorov has joined the core team and we have no plans to stop expanding!

Dysprosium-M1 is available on our milestone repository. It is paving the way for more changes in the work. It's worth noting that 2 features are being deprecated, and evaluated for removal at the…

The 8th Service Release for Californium is out. Beyond fixing its share of issues, it is shipping with a turbo-charged reactor-netty -thanks to changes backported- from our new Dysprosium-M1 release.

The release is available on your preferred maven central repository.

Change logs and release notes:

• reactor-core 3.2.9.RELEASE
• reactor-netty 0.8.8.RELEASE

Note that the release overrides Californium-SR7 which has shipped with an unwelcome regression in reactor-netty 0.8.7.

Bismuth EOL

Anticipating the coming Dysprosium-RELEASE, our reactor-core 3.1.x and reactor-netty 0.7.x lines will not receive further patches. We encourage our users to update to Californium releases trains, which match Spring Boot 2.1.x and Spring Framework 5.1.x…

Hi Spring fans! Welcome to another installment of This Week in Spring! I'm in beautiful Krakow for the epic Geecon show and then I'm off to spectacular Barcelona, Spain for the Spring I/O show. I hope to see you in both locations! It's sure to be fun. Next week it's going to be even more crazy! Next week I'm off to Zurich, Switzerland for a visit with some customers, and then it's off to Paris, France for the Spring One Tour event there, and then it's off to Minsk, Belarus, for the VOXXED Days Minsk show (my first time there! I'm so excited!), and then right after that, it's off to Barcelona…

Today it’s my pleasure to announce General Availability of Spring Integration for Amazon Web Services extension version 2.2.0 and Spring Cloud Stream Binder for AWS Kinesis version 1.2.0.

These releases can be downloaded from Maven Central, JCenter, and our release repository:

compile "org.springframework.integration:spring-integration-aws:2.2.0.RELEASE"

If you don’t use Kinesis Binder. Or via Binder dependency:

compile "org.springframework.cloud:spring-cloud-stream-binder-kinesis:1.2.0.RELEASE"

The main theme of both these releases is about new functionality to support Kinesis Client and Kinesis Producer libraries. For this purpose the spring-integration-aws is shipped with KclMessageDrivenChannelAdapter and KplMessageHandler implementations, respectively. At the moment an implementation is based on the KCL v1.x, since not all AWS dependencies we use in the spring-integration-aws provide the AWS SKD v2 implementation. Based on the Kinesis Client Library investigation, an additional CheckpointMode.periodic has been introduced to both KclMessageDrivenChannelAdapter and …

I am pleased to announce that Spring Batch 4.2.0.M2 is available now from our milestone repository.

What’s new?

This release adds a new item reader and a new item writer for Apache Kafka:

• KafkaItemReader can read messages from a single partition or multiple partitions of the same topic. This reader stores message offsets in the ExecutionContext to support restart.
• KafkaItemWriter uses a KafkaTemplate from the Spring for Apache Kafka project to send messages to a given topic.

I would like to thank Mathieu Ouellet for his amazing contribution in adding support for Apache Kafka in Spring Batch!

We are pleased to announce the availability of the second milestone of the Spring for Apache Kafka 2.3 release - 2.3.0.M2.

Highlights

• The new RecoveringDeserializationExceptionHandler can recover from failed deserialization operations in Kafka Streams applications, for example to send the failed message to a dead-letter topic.

• The new HeaderEnricher transformer can be added to a Kafka Streams topology to add headers.

• The new MessagingTransformer can be used to invoke a Spring Integration flow within a Kafka Streams topology.

• The new AggregatingReplyingKafkaTemplate can send a record and wait for responses from multiple consumers.
