MINIFICPP-31 Added UpdateAttribute processor
----
> Support UpdateAttribute for nifi-minifi-cpp
> -------------------------------------------
>
> Key: MINIFICPP-31
> URL: https://issues.apache.org/jira/browse/MINIFICPP-31
> Project: NiFi MiNiFi C++
> Issue Type: New Feature
> Reporter: Randy Gelhausen
> Assignee: Andrew Christianson
> Priority: Major
>
> nifi-minifi-cpp agents can generate multiple "streams" of flowfiles.
> For instance, to monitor a host, nifi-minifi-cpp runs nmon, ps, netstat, and
> gathers logfiles from applications.
> But, for a given flowfile, any downstream NiFi collectors wont have
> visibility into the originating hostname, nor metadata about which "stream"
> (ExecuteProcess(nmon), ExecuteProcess(ps), TailFile(app1), TailFile(app2))
> generated it.
> One solution is to use a separate InputPort for each stream. This works, but
> burdens both the team working on agent flows, and the team managing the
> collector- they have to be in concert.
> A simpler (better?) approach is to allow agent teams to tag flowfiles with
> differentiating metadata via use of UpdateAttribute.
