Developing Order Management System (OMS) Using Spring, Apache Camel and Saga Pattern | Part 1

Introduction:

In this example, we will build a full order management system using Spring Boot, Apache Camel, the Saga design pattern, and CQRS. We will learn about the best practices for building a highly available and scalable order management system. But before we dive deep into the implementation, let’s briefly understand a few concepts and technologies we will be using in this implementation.

1. Spring Boot:
   Spring Boot will serve as the backend platform for building our microservices.
2. Apache Camel:
   Apache Camel will play a crucial role as the integration pattern between our services. It offers a versatile range of integration options, including Kafka, REST, and file-based communication. This flexibility allows seamless communication and data exchange among different components of our system, ensuring efficient and reliable integration.
3. Saga Pattern:
   The Saga design pattern plays a crucial role in orchestrating transactions between distributed systems. It manages the lifecycle of transactions, including rollbacks and compensations, ensuring consistency and reliability across our system.
4. CQRS Pattern:
   The CQRS pattern, or Command Query Responsibility Segregation, is a design pattern that separates read queries from write queries. This distinction is vital because it allows us to cater to different user roles and permissions effectively. By…
