For the vast majority of my data usage eventual consistency is fine (i.e. CL=ONE) but I have a small amount of critical data for which I read and write using CL=QUORUM.
If I have a cluster with 3 nodes and RF=2, and CL=QUORUM does that mean that a value can be read from or written to any 2 nodes, or does it have to be the particular 2 nodes that store the data? If it is the particular 2 nodes that store the data, that means that I can't even take down one node, since it will be the mandatory 2nd node for 1/3 of my data...
