Subject Re: NiFi Extension Registry?
Date Tue, 15 Oct 2019 19:09:34 GMT
Thanks for the kind words Shalin. This is something that is in development as Bryan mentioned.
It’s a great time to contribute ideas and suggestions, as well as get involved with contributing
code if you’re interested. We always welcome input from the community, especially if you
have a real world use case for this with specific requirements and scenarios. That will help
us build something that doesn’t just check off features, but solves real problems.
