Purpose

A comma-separated list of member nodes in your cluster to which the driver attempts to connect. Specifying a value for this property enables connection failover and load balancing when connecting to a cluster.

Valid Values

server_name | port_number [, ...]

where:

server_name
is the name of a server for a member node or the IP address of the server for a member node in the replica-set cluster to which you want to connect.
port_number

is the port number of the server listener for the corresponding member node.

For example:

server1:9042,255.125.1.11:9043,"2001:DB8:0000:0000:8:800:200C:417A":9044

Notes

  • When specifying a value for this property, the driver randomly selects from the list for a server node to first attempt a connection. If that connection fails, the driver again randomly selects another server node from this list until all servers in the list have been tried or a connection is successfully established.
