I'm not sure, that selecting node upon DS is a good idea. First of all every node has values about every node, including self. Self DS values are always better than others.
For example, 3 nodes RF=2: N1 N2 N3 N1 0.5ms 2ms 2ms N2 2ms 0.5ms 2ms N3 2ms 2ms 0.5ms We have monitored many Cassandra counters, including DS values for every node, and graphs shows that latencies is not about load. So the strategy should be based on use case, node count, RF, replica placement strategy, read repair chance, and more, and more... What do you want to achieve?
