"Perfectly supported" seems a bit expansive as a claim. They are not quite
the same thing as actual dynamic columns and are meaningfully worse in some

Rational people should presume that Thrift support must eventually

projects at Eventbrite examine using CQL3 as soon as I deploy 2.0, which
will probably be in mid-2015.
