https://github.com/apache/nifi/pull/2820
In Nifi, they way that the template would be done, is not through a
Processor, but instead you would implement this functionality as a RecordReader
with a set schema ( like the syslog schemas ). Then you could choose to write
the data with the schema included in the avro.
Sending a template is not something that processors in standard nifi
usually do, it will be enough to just document the schema in the
additionalDetails.html documentation.
When this processor lands, I think I'm going to do the RecordReader.
Then again, we should get someone else's opinion. @bbende can you chime
in here?

> Key: NIFI-5327
> URL: https://issues.apache.org/jira/browse/NIFI-5327
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Core Framework
> Affects Versions: 1.6.0
> Reporter: Prashanth Venkatesan
> Assignee: Prashanth Venkatesan
> Priority: Major
>
> As network traffic data scopes for the big data use case, would like NiFi to
> have processors to support parsing of those protocols.
> Netflow is a protocol introduced by Cisco that provides the ability to
> collect IP network traffic as it enters or exits an interface and is
> described in detail in here:
> [https://www.cisco.com/c/en/us/td/docs/net_mgmt/netflow_collection_engine/3-6/user/guide/format.html]
>
> Currently, I have created the following processor:
> *ParseNetflowv5*: Parses the ingress netflowv5 bytes and ingest as either
> NiFi flowfile attributes or as a JSON content. This also sends
> one-time-template.
>
> Further ahead, we can add many processor specific to network protocols in
> this nar bundle.
> I will create a pull request.
