Transaction Management: Propagation & Isolation #30

The query

SQL

-- Q: How do you handle complex transactions in Spring Boot? (Case 30)
@Transactional(isolation = Isolation.READ_COMMITTED, propagation = Propagation.REQUIRES_NEW)
public void processPayment() { ... }

Tested against PostgreSQL 16

Note

“PostgreSQL default isolation is READ COMMITTED. Changing to SERIALIZABLE prevents serialization anomalies but causes retries.
