How do you manage Transactions in Clean Architecture?
Updated Apr 28, 2026
Short answer
Transactions should be managed at the Use Case level, often through a Unit of Work interface.
Deep explanation
Since a Use Case defines a single atomic action (like 'Place Order'), it must ensure that all database operations succeed or fail together. We define a 'Unit of Work' interface in the Use Case layer, which the Infrastructure layer implements using database transactions.
Real-world example
Transferring money between two bank accounts requires both a debit and a credit to succeed.
Common mistakes
- Putting transaction logic (like @Transactional annotations) inside the Entity classes.
Follow-up questions
- Is it okay to have transactions in the Repository layer?
