It enables easy implementation of event-driven architectures and saga patterns, while ensuring reliable message delivery. ## Features **Core Communication:** - **Publish/Subscribe Messaging:** Exchange messages between microservices using a publish-subscribe pattern. - **Headers-Based Routing:** Leverage the power of RabbitMQ's headers exchange for flexible and dynamic routing of messages based on custom headers. - **Durable Exchanges and Queues:** Ensure message persistence and reliability with durable RabbitMQ components. **Saga Management:** <div style="text-align: center;"> <img src="https://raw.githubusercontent.com/legendaryum-metaverse/legend-transactional/main/.github/assets/saga.png" alt="legendaryum" style="width: 90%;"/> </div> - **Saga Orchestration:** Coordinate complex, multi-step transactions across multiple microservices with saga orchestration. - **Saga Step Handlers:** Implement step-by-step saga logic in your microservices using callbacks. - **Compensation Logic:** Define compensating actions for saga steps to handle failures gracefully and maintain data consistency. ## Contributors Thanks to [all contributors](https://github.com/legendaryum-metaverse/legend-transactional/graphs/contributors)! ## Author Jorge Clavijo <https://github.com/jym272> ## License Distributed under the MIT License.
