SpringConcurrencyTransactionsCode Review

More than 100 values are passed to process. An error occurs while processing the last value in the list. Which changes are written to the database?

@Service
public class Processor {

    @Transactional
    public void process(List<String> items) {
        if (CollectionUtils.isEmpty(items)) {
            return;
        }

        items.parallelStream()
                .forEach(this::processItem);
    }

    private void processItem(String item) {
        // insert/update item entity in DB
    }
}
