Spring Cloud Stream - Event Routing

Engineering | Oleg Zhurakousky | October 31, 2019 | ...

Welcome to another post in a series of posts showcasing the new features of Spring Cloud Stream (SCSt). In previous posts (available here, here and here), we tried to provide justification for our shift to a functional programming model in Spring Cloud Stream (SCSt). It is less code and less configuration, and your code remains completely decoupled from the internals of SCSt.

Today, we'll talk about routing with functions. Routing, in the context of SCSt, is the ability to either a) route events to a particular event subscriber or b) route an event produced by an event subscriber to a particular destination. To help more with the context, let's quickly look at how things work in the annotation-based programming model. In this post, we'll refer to it as route 'TO…

This Week in Spring - October 29th, 2019

Engineering | Josh Long | October 29, 2019 | ...

Hi, Spring fans! Welcome to another installment of This Week in Spring! Can you believe we're already staring down November? I can't! (We're just two months away from the new year!) This week I'm in Chicago for meetings, and then - finally - I'm off to San Francisco and see the family. Then, it's off to Europe for the Devoxx Ukraine and Devoxx Belgium events. I can't wait to see everyone there!

I'm particularly looking forward to spending Halloween (on the 31st of October) in San Francisco with my kid. The entire family, including the dog, have Halloween costumes. We're ready! (I'm going…

Spring Cloud Stream - and Spring Integration.

Engineering | Artem Bilan | October 25, 2019 | ...

If you listened to Oleg Zhurakousky's talk at Spring One Platform 2019 about Spring Cloud Stream & Functions or read his recent blog posts about Simplified Spring Cloud Stream and Functional Spring Cloud Stream, you may want to say: "Wait! What happened with Spring Integration support? What do I now do with my @ServiceActivator or IntegrationFlow? I used to deal with the Sink.input() as a channel to consume binder destination with some Spring Integration logic!" As Oleg mentions in his blog post, it is still possible with existing @EnableBinding and so on, but we are moving away from that…

The Reactive Revolution at SpringOne Platform 2019 (part 2/N)

Engineering | Josh Long | October 22, 2019 | ...

Last year right in the middle of SpringOne Platform 2018, I posted the first post in this series, _ The Reactive Revolution at SpringOne Platform 2018 (part 1/N)_, which looked at some of the big features we'd just dropped at SpringOne Platform 2018. I wanted to follow up and revisit that blog and the concepts I'd introduced last year, and show just how far we've come in the intervening year. TL;DR: things are much easier!


Last year, we announced our work on trying to support a standard for reactive SQL data access with a new project called R2DBC. Traditional approaches to SQL data…
