Site to Site Properties

These properties govern how this instance of NiFi communicates with remote instances of NiFi when Remote Process Groups are configured in the dataflow. Remote Process Groups can choose transport protocol from RAW and HTTP. Properties named with nifi.remote.input.socket.* are RAW transport protocol specific. Similarly, nifi.remote.input.http.* are HTTP transport protocol specific properties.



The host name that will be given out to clients to connect to this NiFi instance for Site-to-Site communication. By default, it is the value from InetAddress.getLocalHost().getHostName(). On UNIX-like operating systems, this is typically the output from the hostname command.

This indicates whether communication between this instance of NiFi and remote NiFi instances should be secure. By default, it is set to false. In order for secure site-to-site to work, set the property to true. Many other Security Properties (below) must also be configured.


The remote input socket port for Site-to-Site communication. By default, it is blank, but it must have a value in order to use RAW socket as transport protocol for Site-to-Site.


Specifies whether HTTP Site-to-Site should be enabled on this host. By default, it is set to true.

Whether a Site-to-Site client uses HTTP or HTTPS is determined by If it is set to true, then requests are sent as HTTPS to nifi.web.https.port. If set to false, HTTP requests are sent to nifi.web.http.port.


Specifies how long a transaction can stay alive on the server. By default, it is set to 30 seconds.

If a Site-to-Site client hasn't proceeded to the next action after this period of time, the transaction is discarded from the remote NiFi instance. For example, when a client creates a transaction but doesn't send or receive flow files, or when a client sends or receives flow files but doesn't confirm that transaction.
