YANGFEIRAN commented on NIFI-4000:
----------------------------------
[~ijokarumawak] Thank you so much, I have seen that stateful annotation, it is
configured both in the ListFTP and QueryDatabaseTable processors. So, it is
what I am searching for, from my point of view, I can use the StateManager when
I wanted to change any processor into a stateful one.(Still working on it,
learning how to use the StateManager to code my own stateful processor). Am I
right? If so, this issue can be closed.
> 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
