The Compensating Transaction architecture pattern is a design pattern used in distributed systems to provide a consistent and reliable way of handling failures. This pattern is used when an operation is not fully executed due to an error or a failure, and a way to undo the changes made during the operation is required.
The Compensating Transaction pattern consists of two parts: the main transaction and the compensating transaction. The main transaction performs a series of actions that can modify the state of the system, while the compensating transaction performs the opposite actions required to undo the changes made by the main transaction.
When a failure occurs during the main transaction, the compensating transaction is executed to undo the changes made by the main transaction. This ensures that the system is left in a consistent state, despite the failure.
Overall, the Compensating Transaction pattern provides a robust and fault-tolerant approach to handling errors in distributed systems, ensuring that operations can be safely rolled back in the event of a failure.
