Using this information to automatically adapt the set of nodes used by the client if a new node is added to or respectively removed from the cluster.
Why do you prefer round robin DNS for load balancing? One advantage I see is, that the client does not has to take care about the node set and especially the management of the node set. The reason why I was thinking about a client side load balancing was to avoid the need to write additional tools, to monitor all nodes in the cluster and changing the DNS entry if any node fails - and this as fast as possible to prevent the clients from trying to use a dead node. But the time writing this, I doesn't think anymore, that this is good point. This is just a point of some sort of retry logic, which is needed anyway in the client. Carsten
