The Problem Think about you have a Microservices e-commerce application. One of the most powerful types of transactions is called a Two-Phase Commit, which is in summary when the commit of a first transactions depends on the completion of a second. Let each workers set their own work to completed while the saga effectively polls using delayed messaging to see if all work is done. Does this imply modeling each document write as a distinct event? It was a Thursday. You can rate examples to help us improve the quality of examples.
Without persistent state, a saga would consider each event a new event, and orchestration of subsequent events would be meaningless.

SAGA Choreography If you are about dance, then choreography is a sequence of steps or movements. Alternatively, conduct a self-assessment using the Microservices Assessment Platform. While it has its benefits, the approach brings some added complexity. It consists of video lectures, code labs, and a weekly ask-me-anything video conference repeated in multiple timezones. Since Orders and Customers are in different databases owned by different services the application cannot simply use a local ACID transaction. What about upstream sync though? Implement each business transaction that spans multiple services is a saga. My virtual bootcamp, distributed data patterns in a microservice architecture, is now open for enrollment! The one that I would like to talk about today is called Saga pattern. Therefore, saving state between events is important. Assess your application's microservice architecture and identify what needs to be improved.
