The request is transfer flowfile to a remote nifi server in a FIFO queue. I have tried methods below:
via http InvokeHttp -> ListenHttp. I found that there are few requests has been abandoned, and i notice that i can link "retry" to InvokeHttp itself, but i'm not sure whether the flowfile is still at the top of queue or not.
via ftp PutFtp -> GetFtp. On the get side, the files seems not a FIFO order.
Is there any solutions for this? Thanks!
NiFi can accept remote data in a variety of ways -- listening to HTTP requests, consuming TCP/UDP packets, consuming Kafka topics/queues, (S)FTP, AMQP, etc.
If you specifically want to transmit a flowfile from one NiFi instance to another, the Site-to-Site (S2S) protocol is designed explicitly for this. It makes it very easy to do this. There is even a Java module you can consume in other projects to take advantage of these transmission mechanics.
