How to connect to a particular server group from hotrod client?

[udit-mishra-5113a21a]

Lets say, we have two server groups - "GroupA"  with two nodes "NodeA1" and "NodeA2" and "GroupB" with "NodeB1" and "NodeB2". How to communicate with different groups from hotrod client? I assume that giving any node name/IP from that cluster will be sufficient.

One more thing I would like to know that if we design clusters at server side, by logical grouping under the <server-group>, then why does hotrod client ConfigurationBuilder has got methods like addCluster(), addServers() etc?? When I call addCluster() with an existing <server-group> name, what exactly happens?? What if I give some name which does not exist as a <server-group>??

Yes indeed, with HotRod it is sufficient to give at least the coordinates of one endpoint in the cluster, and it will receive the topology (i.e. server node addresses) automatically.

The addCluster() method in the RemoteCacheManager ConfigurationBuilder is for configuring backup site failover, so that if your primary cluster goes down, the clients can be switched to connect to a remote backup site. It has no relation to server groups.
