[name] asked: do you know the Saga pattern?

The Saga pattern is used for managing distributed transactions in a microservices architecture. It breaks a large transaction into a series of local transactions, each executed in a separate service. If one of the transactions fails, compensating actions are performed to rollback the previous changes.

Example: when placing an order, the item is first reserved, then money is deducted, and finally the order record is created. If the money deduction fails, a compensating action is performed — canceling the reservation of the item.

This approach ensures data consistency without using distributed transactions and locks.
