Event-Driven Architecture in Golang

Overview of this book

Event-driven architecture in Golang is an approach used to develop applications that shares state changes asynchronously, internally, and externally using messages. EDA applications are better suited at handling situations that need to scale up quickly and the chances of individual component failures are less likely to bring your system crashing down. This is why EDA is a great thing to learn and this book is designed to get you started with the help of step-by-step explanations of essential concepts, practical examples, and more. You’ll begin building event-driven microservices, including patterns to handle data consistency and resiliency. Not only will you learn the patterns behind event-driven microservices but also how to communicate using asynchronous messaging with event streams. You’ll then build an application made of several microservices that communicates using both choreographed and orchestrated messaging. By the end of this book, you’ll be able to build and deploy your own event-driven microservices using asynchronous communication.

Message Workflows

In the previous chapter, we used events to share information between the modules. In this chapter, we will learn how complex work can be done in a distributed and asynchronous way. We will introduce several different options for performing complex operations across different components. After that, we will implement a new asynchronous workflow for creating orders in the application using one of those techniques.

In this chapter, we will cover the following topics:

  • What is a distributed transaction?
  • Comparing various methods of distributed transactions
  • Implementing distributed transactions with Sagas
  • Converting the order creation process to use a Saga
