Yup I definitely agree
> File based implementation
> -------------------------
>
> Key: MINIFI-2
> URL: https://issues.apache.org/jira/browse/MINIFI-2
> Project: Apache NiFi MiNiFi
> Issue Type: Sub-task
> Components: Processing Configuration
> Reporter: Aldrin Piri
> Fix For: 0.0.1
>
> Attachments: ConfigFileExplanation.xml, Properties_Guide.md,
> config.yml
>
>
> A defined schema for processing configuration will need to be defined. XML
> or YAML seem like possible options for achieving this.
> Agent configuration will come from two places, a bootstrap properties file
> and a flow configuration file. The bootstrap will make use of some of the
> original nifi.properties in order to start up the agent. The flow
> configuration file will essentially be a stripped down version of a flow.xml
> (with potentially S2S properties from nifi.properties).
> The format for the bootstrap.properties should likely be similar to
> nifi.properties.
> Further, a way to incorporate this to leverage the libraries from core NiFi
> will aid in achieving a proof of concept implementation more expediently.
