             Summary: ListSftp/ListFtp Enhancements for the older files first or newer files first 
                 Key: NIFI-8022
                 URL: https://issues.apache.org/jira/browse/NIFI-8022
             Project: Apache NiFi
          Issue Type: Improvement
            Reporter: Ganesh Boyilla
            Assignee: Ganesh Boyilla


In NIFI, ListSFTP/ListFTP processors supporting an option to choose which files to list first (older/newer) And also this new field should support NiFi Expression Language.

Use case is the following:

We have a flow that is listing and fetching files from an external environment that can have thousands of files to be collected. There is a need to choose (depending on the environment) if we want to collect older files first or newer files first.

We have a process group that we instance with a few set of variables via API, and one of them should be this Transfer New Files First (variable TransferNewFilesFirst)
 With the proposed feature, the ListSFTP/ListFTP processors would have this new field and inherit the variable e.g. ${TransferNewFilesFirst} and use it for listing.
