Spring / Spring Data Access

Describe the purpose of the @Transactional(propagation = Propagation.NESTED) annotation.

The @Transactional(propagation = Propagation.NESTED) annotation is used to define a nested transactional scope in a Spring Boot application. When a method is annotated with this annotation, a nested transaction is created within the current transaction.

The nested transaction behaves as an independent transaction and can be rolled back separately from the outer transaction. If the nested transaction fails, only the changes made within the nested transaction are rolled back, while the outer transaction remains unaffected.
