ListSFTP incoming relationship

[scott]

Hello Devs,

I would like to request a feature to a major processor, ListSFTP. But 
before I do down the official road, I wanted to ask if anyone thought it 
was a terrible idea or impossible, etc. The request is to add support 
for an incoming relationship to the ListSFTP processor specifically, but 
I could see it added to many of the commonly used head processes, such 
as ListFile. I would envision functionality more like InvokeHTTP or 
ExecuteSQL, where an incoming flow file could initiate the action, and 
the attributes in the incoming flow file could be used to configure the 
processor actions. It's the configuration aspect that most appeals to 
me, because it opens it up to being centrally or dynamically configured.

Thanks,

Scott
