             Summary: Support asynchronous session commits in ListenHTTP
                 Key: NIFI-9255
                 URL: https://issues.apache.org/jira/browse/NIFI-9255
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
            Reporter: Peter Turcsanyi
            Assignee: Peter Turcsanyi


ListenHTTP does not support async commits properly because it sends the 
response back when the servlet's service method exits and it can happen before 
the async commit actually gets executed. It does not provide at least once 
guarantee, because the commit may fail after the successful response sent out.

It does not affect stateful NiFi where the commit is executed synchronously (so 
before the servlet's service method terminated) but can cause issues in 
Stateless NiFi.
