Subject Re: Regarding Rowkey and Column Family
Date Mon, 24 Dec 2012 13:15:08 GMT
it is. but why do you want  to do that? you will run into issues once your
data starts growing. each cell, along with the actual value stores few
additional things, *row, column *and the *version. *as a result you will
loose space if you do that.
