Hi All,

Thanks

I was trying to understand the difference between LIstenTCP and GetTCP, my understanding is that getTCP pulls tha data and listenTCP we have to push the data, is there any other difference?

Thanks

The GetTCP processor does not pull the data, it simply connects to the configured endpoint and then reads the data on that endpoint.

The ListenTCP processor waits for the incoming TCP connection and then reads the data.

GetTCP - Connects over TCP to the provided endpoint(s). Received data will be written as content to the FlowFile

ListenTCP- Listens for incoming TCP connections and reads data from each connection using a line separator as the message demarcator.

What do you mean "pull the data" and "reads the data" with GetTCP processor?
