The microservice architecture structures an application as a set of loosely coupled, collaborating services. Maintaining data consistency is challenging since each service has its own database to ensure loose coupling. To make matters worse, for a variety of reasons distributed transactions using JTA are not an option for modern applications.
In this talk Chris Richardson describes an alternative transaction model known as a saga. You will learn about the benefits and drawbacks of using sagas. Chris describes how sagas are eventually consistent rather than ACID and what this means for developers. You will learn how to design and implement sagas in a Java application.
