New Contributor

I was looking if we an api or some feature, that list files older than x days for a nifi url and corresponding queue id.

Anything you can do via the NiFi canvas, you can also accomplish via the rest-api.

So you can create a queue listing via a rest-api call:

curl http://<nifi-hostname>:<port>/nifi-api/flowfile-queues/<connection-uuid>/listing-requests

The above call will return a response that includes the URL you need to use to retrieve those results.

for example:


Then query for the listings results

curl http://<nifi-hostname>:<port>/nifi-api/flowfile-queues/<connection-uuid>/listing-requests/1d98d557-0171-1000-ffff-ffffd559ca47

This return a json with all the FlowFiles from that specific connection queue from all nodes in your NiFi cluster.  That json would need to be parsed for info like nodes where the "lineageDuration" epoch time is x amount of time older then now, the "clusterNodeAddress" (which node holds the file), and maybe filename".

and then delete the queue listing when done. (this is important or it stays around using heap space).

curl -X DELETE http://<nifi-hostname>:<port>/nifi-api/flowfile-queues/<connection-uuid>/listing-requests/1d98d557-0171-1000-ffff-ffffd559ca47

Hope this helps,
