Microservices saga pattern

Microservice Saga Pattern

Microservice Saga Patten using RabbitMQ. There are two types of architecture for this pattern: Choreography and Orchestration. For this example, I used the Choreography one.

I did not create the product microservice. Products will be saveed in the stock-service.

The management plugin is included in the RabbitMQ distribution. It must be enabled before it can be used:

rabbitmq-plugins enable rabbitmq_management

http://localhost:15672/

To import definitions using rabbitmqctl, use:

rabbitmqctl import_definitions /path/rabbitmq-definitions.json
