             Summary: create NiFI sub projects to host NiFi REST client in different languages
                 Key: NIFI-7718
                 URL: https://issues.apache.org/jira/browse/NIFI-7718
             Project: Apache NiFi
          Issue Type: New Feature
          Components: Tools and Build
            Reporter: Simon Weng


We're seeing the need of NiFI REST clients in different languages, such as Python, Go, etc, so that software can be created to control and manage NiFi cluster and flows.

Since the RESTful API is documented in OpenAPI spec v2, a client SDK can be generated via [openapi-generator|[https://github.com/OpenAPITools/openapi-generator]|https://github.com/OpenAPITools/openapi-generator].]

Individual effort is seen from the community, such as:
 * [https://github.com/erdrix/nigoapi]
 * [https://github.com/simingweng/nifi-go-client]
 * [https://github.com/Chaffelson/nipyapi]

It would be beneficial to the community to consolidate the effort and centrally maintain the Client SDK effort for everybody to use.

Just like \{{minifi}} being a sub project of NiFi, we can create sub project for each language binding, such as:
 * apache/nifi-client-go
 * apache/nifi-client-python

A \{{repo-per-language}} approach is favored for various reasons, take [https://github.com/kubernetes-client] as sample:
 * each language has its idiomatic way to publish and share
 * easier for contributor to maintain and release
 * each language may require different custom templates, almost certainly different code generation configurations
 * some language has tighter couple with repo and their dependencies management, like Go

This means higher initial logistic effort to set those sub projects up, but it can be done gradually.
