Something similar to https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/transaction/annotation/Propagation.html

@Tapac is there a way to ...

1. suspend the current transaction
2. create a new transaction -> (force) commit the new transaction
3. resume the initial transaction

Currently, I struggle with that. It might be similar the spring TransactionPropagation.REQUIRES_NEW .

My current use case (pseudo code) ...

fun handle() {

outer= transaction.start()
Try {
   outer.exec(some sql)
   
  Try {
      inner = transaction.start()
      inner.exec(sql)
      inner.commit()
  }

}
.onSuccess() { outer.commit() }

.onFailure() { outer.rollback() } // outer: rollback, but inner should be commited.

}

Thanks a lot for your help :)

I was trying to commit nested transaction with set up useNestedTransactions == true for Database but that did not work. This indeed is nice to have feature.
