I am pleased to announce that Spring for Apache Kafka 2.2.0.RELEASE is now available.

While the 2.1.x release is compatible with the 2.0.0 kafka-clients jar, (since 2.1.9), this version requires 2.0.0 (and provides a 2.0.0 embedded broker for testing).

Highlights

• The SeekToCurrentErrorHandler can now "skip" records that fail repeatedly

• Such "skipped" records can be published to a dead-letter topic (or otherwise disposed of by application code)

  • Headers are added with diagnostics about the failure

• When using transactions, the same functionality can be achieved with the default AfterRollbackProcessor

• You can now use the listener container factory to create any arbitrary listener container, not just containers for @KafkaListener s

  • This allows more convenient use of Spring Boot’s auto configuration properties for any container

• @KafkaListener annotations can now override the container factory’s concurrency and autoStartup properties

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I've just flown back from Canada and Russia where I was at the amazing Joker conference in St. Petersburg. I'm now in San Francisco (where I live!) for a couple of days to soak up the amazing atmosphere around Oracle CodeOne, reunited with the Java community and longtime friends. I'm so excited about the presentation that fellow Java Champion Trisha Gee and I are doing tomorrow at 11:30 am that introduces an end-to-end reactive and Spring-based application from JavaFX client to service. Do not miss this!

Spring Cloud Function has a couple of new features in 2.0 (still in milestone phase), and possibly the most dramatic is the ability to go "fully functional". This is made possible by changes in Spring Boot 2.1 together with Spring Framework 5.1, and it means a different way of thinking about bean definitions in Spring applications, but also significant improvements in startup performance.

AWS Cost Savings

It’s always good to start with a picture, especially if it tells a story. Here’s a graph that shows the improvement in Spring Cloud Function 2.0 over 1.0, comparing the cost of cold starts in…
