Okay, I see. But isn't there a big issue for scaling here ? Imagine that I am the developper of a certain very successful website : At year 1 I need 20 CF. I might need to have 8Gb of RAM. Year 2 I need 50 CF because I added functionalities to my wonderful webiste will I need 20 Gb of RAM ? And if at year three I had 300 Column families, will I need 120 Gb of ram / node ? Or did I miss something about memory consuption ?
