What problem does it solve?
This Skill unit provides guidance on implementing Saga-based distributed consistency in Spring Boot 4, which is crucial for coordinating compensating transactions and designing choreography and orchestration flows across microservices.
Core Features & Use Cases
- Distributed Transactions: Implements distributed transactions across microservices using the Saga Pattern.
- Compensating Transactions: Handles transaction rollback when a service fails and ensures eventual consistency in microservices architecture.
- Choreography and Orchestration: Supports both choreography (event-driven) and orchestration (centralized coordinator) approaches with Kafka, RabbitMQ, or Axon Framework.
- Use Case: For example, you can use this Skill to design a saga that coordinates the order creation process across multiple services, handling payment, inventory management, and shipping.
Quick Start
Use the 'spring-boot-saga-pattern' skill to implement a saga for handling a complex business process, such as order processing, by following these steps:
- Design the transaction flow with its compensating transactions.
- Choose the implementation approach (choreography or orchestration).
- Implement services with local transactions and compensating transactions.
- Set up a message broker and configure it for transactional ID and exactly-once semantics.
- Implement the Saga Orchestrator or Event Handlers as needed.
