Part 1: Introduction to Transactions in Spring Cloud Stream Kafka Applications

Part 2: Producer Initiated Transactions in Spring Cloud Stream Kafka Applications

Part 3: Synchronizing with External Transaction Managers in Spring Cloud Stream Kafka Applications

In the last three sections of this blog series, we analyzed how transactions work in Spring Cloud Stream Kafka applications. We encountered different contexts in which transactions are helpful, including both producer and consumer applications and how an application can correctly use them. Now that those fundamental elements are behind us, let’s move on to another aspect of transactions: rolling back a transaction when an error occurs. When an error occurs and a transactional system cannot commit the transaction, the transaction manager rolls back the transaction and does not persist anything for a downstream consumer to see. It would help if an application could dictate how this rollback mechanism works. Spring Cloud Stream facilitates this rollback…

Hi, Spring fans! Welcome to another installment of This Week in Spring! Last week I was in Antwerp, Belgium, for the amazing Devoxx Belgium event, and this week I've been in Amsterdam for the SpringOne Tour Amsterdam stop and - in the middle of the SpringOne Tour Amsterdam event - I dipped out to join my friend and fellow Java Champion Trustin Lee (@trustin) (he created Netty! the guy's a living legend!) for a discussion and ask-me-anything at the local Amsterdam Java User Group, hosted by fellow Java Champion and local Geertjan Wielenga (@GeertjanW). It was a lovely day indeed across the two…

Hi, Spring fans! In this installment, we'll talk to Spring Data legend Greg Turnquist (@gregturn) about the incredible next-level optimizations and query enhancements, the work in general, and so much more. Recorded live at SpringOne 2023 in Las Vegas!

Part 2: Producer Initiated Transactions in Spring Cloud Stream Kafka Applications

In the previous part of this blog series, we saw the basics of transaction management, primarily when using producer-initiated Spring Cloud Stream Kafka applications. In that discussion, we also briefly saw how a Spring Cloud Stream Kafka consumer application could consume records produced transactionally with proper isolation levels. When you synchronize with external transaction managers, such as one…

Hi Spring fans! Welcome to another installment of This Week in Spring! How're you doin'? I've just flown in from Singapore - where I was keynoting and presenting at SpringOne Singapore - and am now in Antwerp, Belgium for the deliriously fun Devoxx Belgium show. I've missed this show, and it's a true pleasure to be back here! Next week, I'll be in Amsterdam, just next door, for the SpringOne Tour Amsterdam. If you're there, come out and say hi!

We've got a lot of stuff to look at this morning, so let's dive right into it.

Part 1: Introduction to Transactions in Spring Cloud Stream Kafka Applications

This article is part 2 of the blog series in which we look at transactions in detail with Spring Cloud Stream and Apache Kafka. We saw a general introduction to transactions in the previous part, touching on the fundamental ideas. In this part of the blog series, we get to the metal by seeing a few implementation details and their practical aspects.

In this article, we largely stay on the producer's side to understand how transactions work with Spring Cloud Stream and Apache Kafka.

…

We are starting a new blog series that focuses on working with transactions in Spring Cloud Stream Kafka applications. This blog series covers many low-level details of writing transactional applications with Spring Cloud Stream and Apache Kafka. By the end of this blog series, we hope to give you enough information about writing transactional Spring Cloud Stream Kafka applications for various business use cases.

Basic Building Blocks

The foundational support for transactions in Spring Cloud Stream Kafka applications primarily comes from Apache Kafka itself and the Spring for Apache Kafka…

Hi, Spring fans! Welcome to another installment of This Week in Spring! How are you? It's September 26th, 2023, and I am in sunny Singapore for SpringOne at VMWare Explore Singapore. If you're around, don't forget to say hi!

It's gonna be a fun and busy week in Singapore, and then next week I'm off to Antwerp, Belgium, for the amazing Devoxx BE 2023. Then, I'm off to Morocco, for Devoxx MA 2023. Then, I'm off to Amsterdam for SpringOne Tour Amsterdam. If you're in any of these places, do not hesitate to reach out and say hi! I'd love to chat! And with that, we've got a ton of things to cover…
