Spring transaction REQUIRED vs REQUIRES_NEW : Rollback Transaction

Question

I have a method that has the propagation = Propagation.REQUIRES_NEW transactional property:

@Transactional(propagation = Propagation.REQUIRES_NEW)
p         


        

Answer 1

If you really need to do it in separate transaction you need to use REQUIRES_NEW and live with the performance overhead. Watch out for dead locks.

I'd rather do it the other way:

• Validate data on Java side.
• Run everyting in one transaction.
• If anything goes wrong on DB side -> it's a major error of DB or validation design. Rollback everything and throw critical top level error.
• Write good unit tests.
