This article is part of a blog series that explores the newly redesigned Spring Cloud Stream applications based on Java Functions. In this episode, we are taking a deeper look into the file supplier and its Spring Cloud Stream file source counterpart. We will also see a MongoDB consumer and its corresponding Spring Cloud Stream sink. Finally, we will demonstrate how the File source and the MongoDB sink can be orchestrated together on Spring Cloud Data Flow as a pipeline.

Here are all the previous parts of this blog series.

• Introducing Function Based Streaming Applications

• Function Composition with Streaming Applications

• How to Build a Supplier and Source Application

• How to Build a Consumer and Sink Application

• Build and Run a Simple Stream Application

• Case Study: HTTP Request Function and Processor

Hi, Spring fans! In this episode, Josh Long (@starbuxman) talks to Google Cloud's Elena Felder (@hellata) about building Reactor/Spring-based integrations for Google Cloud technologies like Google Cloud Spanner.

Hi, Spring fans! Well, here we are! Nearing the end of August 2020! I can't believe it! September follows August (last I checked) and with September comes SpringOne 2020! I am so excited about this mega (and virtual) event and I hope you'll consider joining us there!

On a personal note, today's moving day for my family and me, so I have to get back to that. But we do have a ton to get to so let's dive into it.

Introduction

We began this series by introducing the new stream applications based on Java functions, and function composition. The previous entry presented a tutorial for building a simple stream application and running it in Spring Cloud Data Flow. Today we explore the HTTP Request Function and present examples of how to use it.

This is an update to the original blog post about creating docker images with Spring Boot 2.3. There were a few things related to image creation that changed between the first milestone of Spring Boot 2.3 and the GA release.

The two new features introduced in Spring Boot 2.3 to help improve image creation techniques were: layered jars and buildpack support.

Layered Jars

The layered jar feature evolved quite a bit as we started adding support for custom layers. While the need to express layers that the jar should be split into for image creation was evident, changing the format of the jar to do so no longer seemed necessary. Spring Boot 2.3 includes support for layering a jar using a layers.idx file. The layers index file provides a list of layers and the parts of the jar that should be…

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.
