Right. That comes with the downside of picking one :) It does not seem
the compact storage is the default choice for the the future. As well as
interop with the thrift/cli world, I also find it hard to reason about
row caching with CQL defined tables. I still work through thrift/cli as
a result, which is a pity because CQL has a nice surface.
