This one I fixed while I was in there, the only thing that calls it is
InvokeHttp which passes in true, so it hasn't been a bug, but it could be some
day :P
> Allow StandardProcessSession to calculate duration for provenance events
> ------------------------------------------------------------------------
>
> Key: NIFI-5420
> URL: https://issues.apache.org/jira/browse/NIFI-5420
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Reporter: Matt Burgess
> Assignee: Matt Burgess
> Priority: Major
>
> Besides some automatic provenance events being emitted by the framework, the
> onus is on each processor to register provenance events and to provide a
> duration for the amount of time spent on the operation that results in the
> provenance event(s). However, supplying the duration is not mandatory, and if
> not provided, a value of -1 is stored to indicate that the duration is
> unknown.
> Unfortunately there are many processors that do not track the operation time
> and thus do not store it in the provenance event. However, the time from when
> a flow file is fetched or created in a session to the time the provenance
> event is recorded is a legitimate measure of the time the flow file spent
> "active" in the session, which is the same as the duration of a provenance
> event.
> This Jira proposes to record the "start" time of each flow file (more
> specifically, it's StandardRepositoryRecord), and upon session.commit(),
> record the duration of the flow file while active in the session into the
> provenance event(s), only if the duration has not already been supplied to
> the provenance events.
