Hi, Spring fans!

How's things? I am super happy to talk to you! How's things? Me, I'm alright. Just published a new edition of the Reactive Spring book with a whopping 70+ page on RSocket.

And, of course, I am doing a 2-day long training for YOW! conference starting Thursday (PST)/Friday (in Australia). It's never too late to register for that!.

Introduction

So far in this series we have introduced the new stream applications based on Java functions, and function composition. We have also provided detailed examples of how to build a source from a supplier and a sink from a consumer. Here we continue the journey with the first of several case studies to follow. Each case study demonstrates how to use one or more of the available pre-packaged Spring Boot stream applications, in various scenarios, to build data streaming pipelines.

Today we will showcase two of the most commonly used applications, the HTTP source and the JDBC sink. We will use them to build a simple service that accepts HTTP POST requests and saves the contents to a database table. We will first run these as standalone Spring Cloud Stream applications, and then show how to orchestrate the same pipeline with Spring Cloud Data Flow…
