What is the Unit of Work pattern in event-driven architecture?

The Unit of Work pattern is a design pattern that helps manage transactions in event-driven systems. It ensures that a series of operations are completed successfully before committing changes, maintaining data integrity.

Can you give me an example of how it works?

Sure! Imagine an e-commerce application where a user places an order. The Unit of Work would handle the order creation, inventory update, and payment processing as a single transaction. If any step fails, none of the changes are applied.

What are the benefits of using this pattern?

The main benefits include improved data consistency, easier rollback of changes, and better management of complex transactions across multiple aggregates.

Are there any drawbacks to consider?

Yes, potential drawbacks include increased complexity in implementation and the risk of performance bottlenecks if not managed properly.
