Vamsi Gummalla commented on NIFI-3560:
--------------------------------------
Use case that I am thinking is to automate the ftp process, as in if there is
any change in number of ftp sites or any of the ftp parameters, it is easy to
have UI update the config file to implement the changes. Otherwise for every
change, manually we have to edit the flow file especially in scenario there is
constant change in adding or remove the ftp server.
It is similar for ListFile or ListHDFS, if there are multiple absolute paths
then constant chopping and changing requires to edit flow files then editing
config files.
> Improvement needed for all List Processors

> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Affects Versions: 1.1.1
> Reporter: Vamsi Gummalla
>
> Current Implementation of List processor is such that they can be run in a
> loop.
> Example Use case:- If we need to monitor 100 FTP servers, we have to create
> 100 ListFTP processor rather having one ListFTP processor which can get
> required fields as input and loop it.
