I think Cassandra is a very interesting database but there a re a couple of things I don't understand.
My plan is to have several Mac minis with one Cassandra node on each Mac mini. If one of my Mac minis will fail I want others to take over. Several nodes will also help me to load balance. I think that is exactly what Cassandra is built to do but… What do you guys suggest in front of Cassandra? Round-Robin or something else? I know that DynDNS have Round Robin in their Dynect platform but it's very expensive. I need a cheaper way.
