---------------------------------
Summary: Sleep not used judiciously
Key: MINIFI-209
URL: https://issues.apache.org/jira/browse/MINIFI-209
Project: Apache NiFi MiNiFi
Issue Type: Bug
Components: C++
Affects Versions: 0.1.0
Reporter: marco polo
Fix For: 0.2.0
void TimerDrivenSchedulingAgent::run(Processor *processor) attempts to use
sleep as a flow control mechanism. An alternative would be to use condition
variables to know when work is available and when to play fair.
I don't tend to like sleep based yields since you have no concept of what work
is available to run. Yield would be a preference as the I/O schedule will do a
better job at determining which thread should run; however, we should
investigate the cost/benefit of using a condition variable's notification
mechanism.
I'm labeling this a bug since I've seen cases where no work was being performed
for a period of time. This doesn't make sense as a timer can be achieved more
intelligently with another mechanism.
