Presentation: Data Consistency in Microservice Using Sagas

Track: Microservices: Patterns and Practices

Location: Ballroom A

Day of week:

Slides: Download Slides

Level: Intermediate

Persona: Architect, Backend Developer, Developer, General Software

Abstract

The services in a microservice architecture must be loosely coupled and so cannot share database tables. What’s more, two phase commit (a.k.a. a distributed transaction) is not a viable option for modern applications. Consequently, a microservices application must use the Saga pattern, which maintains data consistency using a series of local transactions.

In this presentation, you will learn how sagas work and how they differ from traditional transactions. We describe how to use sagas to develop business logic in a microservices application. You will learn effective techniques for orchestrating sagas and how to use messaging for reliability. We will describe the design of a saga framework for Java and show a sample application.
