--------------------------------
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.
