             Summary: NiFi uses quite a bit of CPU even when it has nothing to do
                 Key: NIFI-1111
                 URL: https://issues.apache.org/jira/browse/NIFI-1111
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
            Reporter: Mark Payne
            Assignee: Mark Payne
             Fix For: 0.4.0


When a Processor is unable to perform any work, it has the ability to "yield," or pause itself so that it does not chew up resources while it's unable to do anything useful. It appears, though, that even when a Processor is yielded, it uses a lot of CPU. Adding some logging shows that this is due to Processors continually checking if there is work to do, even when they are yielded. This can be improved.
