Hi Team,


Storm has transactional topologies which ensure exactly once delivery. Is there a concept of rollback in transactions ? Does storm support this ?

His transaction mechanism, through the batch processing, when all treatment success submitted. When the failure of batch process, it is not submitted. So, don't worry about the rollback problem. Because of the data submitted, are processed successfully. 
 
Hope that the answer can help you.
