Saga (2/2) - a real life example of Saga pattern One real-life example of where a Saga pattern could be useful is in E-commerce, think an order through Amazon. For example, consider a simple online order process: 1. The user places an order. 2. The system charges the user’s account. 3. The system prepares the delivery of the item. If any of these local transactions fail, the Saga would then execute compensating transactions to undo any previous transactions. For example, if charging the user’s account fails, a compensating transaction would be executed to cancel the order. The challenge with the Saga pattern is maintaining data consistency and handling failures. Also, defining and implementing compensating transactions could be complex depending on the business logic.
