     [ https://issues.apache.org/jira/browse/NIFI-1021?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Oleg Zhurakousky updated NIFI-1021:
-----------------------------------
    Attachment: nifi-provenance-stream-1.0.0-SNAPSHOT.jar

A sample JAR which contains consumer writing events to standard out.
To test, simply drop it into the 'lib' directory of NiFi which is built with proposed changes, start NiFi, create and start any flow and monitor the logs.

> Currently access to the provenance events is exposed thru ReportingTask which is scheduled and therefore provides a "near-real-time" access to provenance events.
> There are several valid use cases where such events may need to be streamed in "real-time" for variety of real time analytics.
