> Key: NIFI-1976
> URL: https://issues.apache.org/jira/browse/NIFI-1976
> Project: Apache NiFi
> Issue Type: Sub-task
> Reporter: Bryan Rosander
>
> Using JNA, we should be able to leverage existing Windows APIs to natively
> consume events as they happen. Will look into subscribing to events
> (https://msdn.microsoft.com/en-us/library/windows/desktop/aa385771(v=vs.85).aspx)
> in order to reduce latency.
