Subject Re: Abnormal memory consumption
Date Mon, 04 Apr 2011 22:24:25 GMT
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 ?

Thank you very much,

Victor
