Just like in Cassandra 2.x, they will show up as COMPACT STORAGE tables in
a format that CQL can work with.  We're making a few adjustments to how the
schema is presented in CQL, mostly to better deal with a mixture of defined
and undefined column names (mixed static and dynamic).  That mostly
involves treating defined columns as "static".

However, the storage format for COMPACT STORAGE tables will not be
(significantly) different from normal tables any more.  You can read a few
details about the new storage format here:
