Koji Kawamura commented on NIFI-4000:
-------------------------------------
[~YANGFEIRAN] It seems that what you'd like to do with GetFTP can be done with
ListFTP and FetchFTP. ListFTP is designed to maintain timestamp for the latest
listed file, so that it can list new files incrementally. FetchFTP can fetch
individual file by referring remote filename using Attribute Expression
Language.
ListFTP is '@Stateful', it stores timestamps to managed state, so that it can
restore the last timestamp it listed before restarting NiFi.
Is there any reason that you need this with GetFTP? If there's, please let us
know. Thank you!
> Auto-Incremental For GetFTP processor

> Key: NIFI-4000
> URL: https://issues.apache.org/jira/browse/NIFI-4000
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Affects Versions: 1.1.1
> Environment: linux
> Reporter: YANGFEIRAN
> Labels: features
>
> Hello,
> I am a NIFI user. When I am using the GetFTP processor, I realized that the
> processor can auto-incrementally import files from FTP only if I configure
> the processor "Delete Original" as "true".
> However, sometimes it is forbidden for me to delete any file in the FTP. So,
> I added a property in the GetFTP and GetFileTransfer processor (it is just a
> property in the JAVA class, can not see it in the UI) in order to record the
> last-modified time for files I have imported. And next time this value can be
> used to filter out those files that I have imported. Never the less, if I
> restart the NIFI, this value will be set back to the beginning.
> I figured out that if I wanted to make it stay still even if NIFI is
> restarted, I have to set this property back to the processor, as those
> properties in the UI. But there is no such a set function, those properties
> as initialized as the processor init.
> Can anyone add a set function, so the property in the UI can change by it
> self as the processor is running? Or it is only me that missing something
> that can achieve this?
> Sorry for my poor English, if I am not clear, just leave comments below.
> Best regards,
> Feiran
