The CUE Zipline cores
communicate with each other via private network connections, using the
network addresses defined in the
configured in the cluster configuration
members list is a list of host name and port
pairs for each instance in the cluster. Each instance opens connections
to the other instances by connecting to these network addresses.
The network address of each instance is defined by the
listen_address property of the
cluster configuration object. The listen address may
be specified as a wild-card (e.g.
0.0.0.0) in order
to listen on all network interfaces.
The port number of the cluster
must be different from the
server port number, because the communication
protocol is different. By default, the server port is
12791 and the cluster listen address port is
The host names and addresses specified in the
list may not be specified as wild cards. They must
be host names that can be resolved or IP addresses, and they must be
accessible to the other instances in the cluster.
