--------------------------------------
GitHub user olegz opened a pull request:
https://github.com/apache/nifi/pull/102
NIFI-1021 added support for Provenance event streaming
SUMMARY:
Current implementation is based on requiring user to implement
org.apache.nifi.provenance.ProvenanceEventConsumer
strategy, declare it as service in META-INF/services and drop the resulting
JAR
in the 'lib' directory of NiFi distribution.
Upon startup each consumer is discovered by ProvenanceRepository via
standard ServiceLoader
after which every provenance event is sent to such consumer.
To simplify things base implementation of ProvenanceRepository was provided
with two existing
implementations modified to extend from it.

> Project: Apache NiFi
> Issue Type: New Feature
> Components: Core Framework
> Affects Versions: 0.3.0
> Reporter: Oleg Zhurakousky
> Assignee: Oleg Zhurakousky
>
> 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.
