# Spring Boot Saga Pattern ## Overview Implements distributed transactions across microservices using the Saga Pattern. Replaces two-phase commit with a sequence of local transactions and compensating actions. Supports choreography (event-driven) and orchestration (centralized coordinator) approaches with Kafka, RabbitMQ, or Axon Framework. ## When to Use - Building distributed transactions across multiple microservices - Replacing two-phase commit (2PC) with a more scalable solution - Handling transaction rollback when a service fails - Ensuring eventual consistency in microservices architecture - Implementing compensating transactions for failed operations - Coordinating complex business processes spanning multiple services **Trigger phrases**: distributed transactions, saga pattern, compensating transactions, microservices transaction, eventual consistency, rollback across services, orchestration pattern, choreography pattern ## Instructions ### 1. Design Transaction Flow Map the sequence of operations and their compensating transactions: ``` Order → Payment → Inventory → Shipment ↓ ↓ ↓ ↓ Cancel Refund Release Cancel ``` **Validation**: Verify every forward step has a corresponding compensation. ### 2. Choose Implementation Approach | Approach | Use Case | Stack | |----------|----------|-------| | Choreography | Greenfield, few participants | Spring Cloud Stream + Kafka/RabbitMQ | | Orchestration | Complex workflows, brownfield | ...
