Hi, Spring fans! In this installment Josh Long (@starbuxman) has RSocket on the brain with his latest talk, RSocket Revolution, the new RSocket chapter in his book Reactive Spring, and the work he’s doing on Spring Retrosocket, a declarative Feign-like RSocket client. Then, Josh talks to Spring ecosystem luminary Maciej Walkowiak (@maciejwalkowiak) about what he’s doing at the helm of Spring Cloud AWS.

• Spring Cloud AWS
• Maciej’s recent video on getting started with Spring Cloud AWS on his excellent YouTube channel Spring Academy
• Josh’s book Reactive Spring has been updated with a new whopping 70+ page chapter on RSocket
• Josh’s The RSocket Revolution talk
• Spring Retrosocket - a declarative client for RSocket à la Feign or Retrofit

On behalf of the team and everyone that contributed, I am pleased to announce that the second milestone of Spring Boot 2.4 has been released and is available from our milestone repository. This release closes just over 250 issues and pull requests.

On behalf of the Spring Batch team, I am pleased to announce that Spring Batch 4.3.0-M2 is now available from our milestone repository.

What’s new?

This release comes with a number of new features and enhancements that you can find in the release notes, but here are the major highlights:

1. Kafka support enhancements

By default, the KafkaItemReader reads a topic from the beginning. When we initially introduced this reader in v4.2, it was not possible to configure it to read records from a custom offset. In this release, we added this feature. As a result of this addition, it is now possible to configure the reader to start from the offset stored in Kafka.

Hi, Spring fans! I have been developing a new talk and I finally got a chance to do a pre-recorded version of it for a keynote for a conference (in China) recently, and want to share the content with you all, so I’m premiering it here, too. This talk, The RSocket Revolution, is about 38 minutes and looks at:

• some of the new features in Spring Boot 2.3x including GraalVM-capable native images
• the basics of RSocket
• fundamentals with RSocket @Controllers in Spring Framework
• Toshiaki Maki’s fantastic rsc RSocket client
• Declarative, Feign-like clients with Spring Retrosocket
• The RSocketRequester to support making requests of RSocket services on the JVM
• Spring Integration’s reactive and RSocket support
• Bidirectional communication - where both client and service separately initiate the communication - using RSocket
• Securing RSocket endpoints with Spring Security and RSocket metadata
