Tell me about SAGA pattern in Microservices

Question

Accepted Answer

SAGA pattern is a design pattern used in microservices architecture to manage distributed transactions.

SAGA pattern breaks down a long-running transaction into a series of smaller, independent transactions.
Each step in the SAGA pattern is a separate service that communicates with other services through events.
If a step fails, compensating transactions are executed to rollback the changes made by previous steps.
Example: In an e-commerce application, the SAGA pattern can be used to handle the order processing flow.
Example: If payment fails, a compensating transaction can be triggered to cancel the order.
