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…

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.
