Well, I'm not an exepert at this (far from it actually) but the way I see it, either you deploy some middleware made by yourself, in order to guarantee the specific properties you are looking for or you can just have Cassandra write data to auxilliary files and then copy them through the file system, since the copy function in Java works as an atomic operation.

I don't know anything about the size of the data files you are considering so I don't really know if it is doable, however there might be a way to use this property through smaller bits of information and then combining them as a whole.

Just my 2 cents...
