Thank you for the fast answer Tylor, I just discover the existence of
the "ColumnSlice" class. I was using phpcassa for a while and didn't
notice about this evolution.

If I want to get just a column should I do :

$slice  = new ColumnSlice('name', 'name');
$result = $cf->get($key, $slice);

or

$result = $cf->get($key, null, array('name'));

Is there any difference on performance between this 2 solution ? Do
they both work ?

Why introducing ColumnSlice ?
